Behavioral development varies greatly from child to child. If you have noticed only wants one parent, here is what you need to know.
The short answer
Parent preference is one of the most common and emotionally painful behaviors in babies and toddlers. It is a completely normal part of attachment development and is not a reflection of who is the "better" parent. Babies and toddlers typically cycle through phases of preferring one parent, and the "rejected" parent's consistent, loving presence during these phases actually strengthens their bond over time.
Key takeaways
- Parent preference is one of the most common and emotionally painful behaviors in babies and toddlers. It is a completely normal part of attachment development and is not a reflection of who is the "better" parent. Babies and toddlers typically cycle through phases of preferring one parent, and the "rejected" parent's consistent, loving presence during these phases actually strengthens their bond over time.
- Usually normal when: Your baby or toddler goes through phases of preferring one parent and it shifts over time
- Call your doctor if: Your child shows sudden fear or avoidance of a parent or caregiver they were previously comfortable with, especially if accompanied by changes in behavior, sleep, or mood
- Varies by age — see the age-by-age breakdown below
Parents everywhere have the same worry. You are doing the right thing by looking into it.
What Parents Should Know
According to AAP, Zero to Three guidelines, parent preference is one of the most common and emotionally painful behaviors in babies and toddlers. It is a completely normal part of attachment development and is not a reflection of who is the "better" parent. Babies and toddlers typically cycle through phases of preferring one parent, and the "rejected" parent's consistent, loving presence during these phases actually strengthens their bond over time. At 0-6 months, young babies may show a natural inclination toward the parent who does the majority of feeding and caregiving, often the nursing mother. This is driven by scent, voice familiarity, and association with food - not by love. The other parent can strengthen their bond through skin-to-skin contact, being the one to do baths or bedtime, and spending focused one-on-one time with the baby. Preference at this age is about familiarity, not rejection. It is generally considered normal when your baby or toddler goes through phases of preferring one parent and it shifts over time. However, you should contact your pediatrician promptly if your child shows sudden fear or avoidance of a parent or caregiver they were previously comfortable with, especially if accompanied by changes in behavior, sleep, or mood.
Normal vs. Concerning
By Age
What to expect by age
0-6 months
Young babies may show a natural inclination toward the parent who does the majority of feeding and caregiving, often the nursing mother. This is driven by scent, voice familiarity, and association with food - not by love. The other parent can strengthen their bond through skin-to-skin contact, being the one to do baths or bedtime, and spending focused one-on-one time with the baby. Preference at this age is about familiarity, not rejection.
6-12 months
As separation anxiety develops around 6-9 months, parent preference often becomes more intense and obvious. A baby may cry or reach for one parent when the other tries to hold them. This can feel devastating for the non-preferred parent, but it is actually a sign of healthy attachment development. The baby is demonstrating that they understand who their primary attachment figure is. The non-preferred parent should continue to be present, warm, and involved - not withdraw.
12-24 months
Toddlers are famous for parent preference that can change suddenly and without warning. Your toddler may insist only mommy can give baths for three months, then switch to demanding daddy exclusively. This is normal and driven by their developing sense of independence and control. Allowing the preferred parent to handle some tasks while the other parent builds their own special routines and rituals helps maintain both relationships.
2-3 years
Parent preference may continue but often becomes less absolute. Toddlers in this age range can begin to understand that both parents are available and each offers something special. If one parent is consistently rejected despite being consistently available and loving, and the child seems genuinely distressed (not just preferential) with that parent, it is worth discussing with your pediatrician to rule out contributing factors.
What to Tell Your Pediatrician
- Describe when you first noticed only wants one parent and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if your child seems genuinely fearful or distressed with one parent (not just preferential), showing signs of anxiety such as trembling, freezing, or avoiding eye contact with that parent specifically.
- Mention if parent preference is so extreme that the non-preferred parent cannot provide any care even when the preferred parent is unavailable, and this has persisted for many months.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Your baby or toddler goes through phases of preferring one parent and it shifts over time
- Your child prefers the parent who is more available or who handles most caregiving tasks like feeding and bedtime
- The preference is stronger when your child is tired, sick, or in an unfamiliar environment
- The "rejected" parent can still comfort the child when the preferred parent is not available
- Your child seems genuinely fearful or distressed with one parent (not just preferential), showing signs of anxiety such as trembling, freezing, or avoiding eye contact with that parent specifically
- Parent preference is so extreme that the non-preferred parent cannot provide any care even when the preferred parent is unavailable, and this has persisted for many months
- The "rejected" parent is experiencing significant depression, feelings of inadequacy, or is withdrawing from the child as a result
- Your child shows sudden fear or avoidance of a parent or caregiver they were previously comfortable with, especially if accompanied by changes in behavior, sleep, or mood
- The family situation has become so strained by parent preference that it is affecting the mental health of one or both parents or the overall family dynamic
What You Can Do at Home
- Keep track of when you notice only wants one parent — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that your baby or toddler goes through phases of preferring one parent and it shifts over time — this is generally within the range of normal.
- At 0-6 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Respond consistently and calmly to your baby's behavior. Maintain predictable daily routines.
- While monitoring at home, seek immediate care if your child shows sudden fear or avoidance of a parent or caregiver they were previously comfortable with, especially if accompanied by changes in behavior, sleep, or mood.

Bonding and Attachment Timeline for Adopted Babies
Bonding with an adopted baby is a real and achievable process, but it may follow a different timeline than biological bonding. Many adoptive parents feel a strong connection quickly, while for others it develops gradually over weeks or months. Consistent, responsive caregiving is the single most important factor in building secure attachment, regardless of how your family was formed.
Aggressive Play vs Normal Play
Rough-and-tumble play — wrestling, chasing, play-fighting, and superhero battles — is a normal and important part of child development, particularly for toddlers and preschoolers. It helps children develop physical coordination, social skills, self-regulation, and an understanding of boundaries. The key distinction between normal rough play and concerning aggression is whether both children are having fun, there is turn-taking in roles, and no one is intentionally trying to hurt the other.
My Toddler Is Aggressive Toward Pets
Toddlers being rough with pets is extremely common and almost never reflects true aggression or cruelty. Young children lack the motor control to be consistently gentle and do not yet understand that animals feel pain the way they do. With patient, consistent teaching about gentle touch and close supervision, most toddlers learn to interact safely with pets by age 3-4.
AI Deepfakes and Your Baby's Photos - Protecting Your Child Online
AI technology has created a new risk for children's photos shared online. NCMEC received over 1.5 million tips related to AI-generated child exploitation material in 2025 - a 2,000% increase from the previous year. Parents' innocent photos of children are being scraped from social media to train AI models or manipulated into harmful content. This does not mean you can never share photos of your child, but it does mean taking precautions: limiting audience, avoiding full-face images in public posts, stripping metadata, and understanding that once a photo is online, you lose control of it.
Raising a Screen-Free Baby: Movement and Analog Play
The AAP recommends no screen time for children under 18 months (except video calls) and limited, high-quality programming for ages 18-24 months with a caregiver. Movement-based and analog play supports healthy brain development, motor skills, and social-emotional growth. Active, hands-on play helps babies build neural connections more effectively than passive screen viewing.
My Baby Doesn't Seem Attached to Anyone
By 7-9 months, most babies show clear preferences for their primary caregivers and some wariness of unfamiliar people. If your baby seems equally comfortable with everyone and shows no distress when separated from caregivers, it may simply reflect an easy-going temperament. However, if combined with other social differences, it can occasionally warrant further discussion with your pediatrician.
