Baby Showing Favoritism to One Parent
Content reviewed against published AAP, NIH guidelines
Last reviewed:
Behavioral development varies greatly from child to child. If you have noticed baby showing favoritism to one parent, here is what you need to know.
The short answer
It is extremely common for babies and toddlers to show a strong preference for one parent, usually the primary caregiver. This is not a reflection of love or bonding quality — it is driven by attachment patterns, routine, and comfort-seeking. The preference often shifts back and forth over time. While it can be painful for the less-preferred parent, it is a normal part of development and typically balances out.
Key takeaways
- It is extremely common for babies and toddlers to show a strong preference for one parent, usually the primary caregiver. This is not a reflection of love or bonding quality — it is driven by attachment patterns, routine, and comfort-seeking. The preference often shifts back and forth over time. While it can be painful for the less-preferred parent, it is a normal part of development and typically balances out.
- Usually normal when: Your baby or toddler cries when the preferred parent leaves the room or hands them to the other parent
- Call your doctor if: Your child shows sudden, unexplained fear of a specific caregiver, especially combined with behavioral changes like sleep disruption, regression, or fearfulness — this warrants immediate discussion with your pediatrician
- Varies by age — see the age-by-age breakdown below
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
0-3 months
Very young babies may seem to prefer whichever parent feeds and holds them most, but this is more about familiarity with scent, voice, and feeding routine than a true preference. Both parents should have regular holding, feeding (if possible), and skin-to-skin time.
3-6 months
Babies begin to show clearer preferences as they recognize faces and voices. A baby who is primarily cared for by one parent may fuss when handed to the other. This is about familiarity and comfort, not rejection. The less-preferred parent should continue regular caregiving without taking it personally.
6-12 months
Separation anxiety peaks around 8-10 months, and babies often become intensely attached to their primary caregiver. They may cry when that parent leaves the room and resist being comforted by anyone else. This is a healthy sign of secure attachment and is temporary.
12 months+
Toddlers may loudly declare their preference ("I want Mommy, not Daddy!") which can be hurtful. Preferences often shift — a child who was "all about mom" may suddenly prefer dad. Building special routines between the less-preferred parent and the child (a special game, bedtime routine, or outing) helps strengthen that bond.

Toddler Jealousy of New Baby
Jealousy toward a new baby is one of the most natural and expected toddler emotions. Your older child has had your undivided attention and is now learning to share it — a monumental adjustment. Jealousy may show up as clinginess, acting out, regression, or even asking to send the baby back. With empathy, dedicated one-on-one time, and patience, most toddlers gradually adapt within a few months.
Social Anxiety at Playgroups
Many toddlers feel anxious in group settings, especially if they are not regularly around other children. Shyness and wariness around unfamiliar people is a normal temperamental trait and a healthy sign of stranger awareness. Most socially cautious toddlers warm up with time and gentle exposure. True social anxiety disorder is rare in toddlers, but persistent, severe avoidance that interferes with daily activities may warrant discussion with your pediatrician.

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.
