Types of Therapy: OT, PT, and Speech
The short answer
The three most common types of therapy for young children are occupational therapy (OT), physical therapy (PT), and speech-language therapy. OT focuses on fine motor skills, sensory processing, and daily activities like feeding and self-care. PT addresses gross motor skills like sitting, crawling, walking, and balance. Speech therapy supports communication, language development, feeding, and swallowing. Many children receive a combination of these therapies based on their individual needs.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
Therapy in the earliest months is often focused on supporting feeding, positioning, and early motor development. For NICU graduates or babies with diagnosed conditions, PT may address muscle tone and head control, while OT may focus on feeding skills and sensory regulation. At this age, therapy is primarily parent coaching, where the therapist teaches you techniques to use throughout your daily routine rather than doing hands-on work only during sessions.
Between 3 and 6 months, therapists may work on skills like reaching, grasping, rolling, and bringing hands together. PT goals often focus on building the core strength needed for sitting, while OT may address fine motor coordination and sensory responses. Speech therapy at this age is less common but may be recommended if there are significant feeding difficulties or if a baby is not vocalizing or responding to sounds as expected.
This is a period of rapid motor development, and therapy goals often focus on sitting independently, crawling, pulling to stand, and beginning to use a pincer grasp. Speech therapy may be introduced if a baby is not babbling, not responding to their name, or having difficulty transitioning to solid foods. All three types of therapy use play as their primary tool, making sessions engaging and natural for your baby.
Toddlers commonly receive speech therapy for late talking, PT for delayed walking or balance concerns, and OT for feeding difficulties or sensory processing challenges. At this age, therapy continues to emphasize parent coaching so that strategies are embedded into everyday activities like mealtimes, bath time, and play. Consistency between therapy sessions and home practice is what drives the most progress.
By age 2-3, therapy goals become more specific and may include combining words into phrases, climbing stairs, using utensils, or managing sensory input in busy environments. As children approach age 3, their therapy may transition from home-based early intervention to a preschool or clinic-based setting. Your therapist and service coordinator will help plan this transition so there is continuity in your child's care.
What Should You Do?
When to take action
- Your child receives a therapy recommendation and you feel uncertain or overwhelmed, which is a natural response to new information about your child's development
- Progress in therapy is gradual and sometimes feels slow, which is typical because developmental skills build on each other over time
- Your child is more cooperative with the therapist than with you at home, or vice versa, which is common and does not mean you are doing anything wrong
- Your therapist adjusts goals and strategies over time as your child develops, which reflects responsive and individualized care
- You are unsure whether your child needs therapy and want your pediatrician's perspective on their development
- Your child has been in therapy for several months and you are not seeing any progress, and want to discuss whether the approach should be adjusted
- You want to understand the difference between what OT, PT, and speech each address so you can better support your child at home
- You are having difficulty accessing therapy services due to insurance, waitlists, or availability in your area
- Your child is losing previously acquired skills such as stopping talking, no longer walking, or losing interest in interacting with others
- Your child has a sudden change in muscle tone, movement, or coordination that was not present before
- Your child is unable to eat or drink safely and is choking, gagging, or aspirating during meals

My Baby's Head Shape Looks Abnormal
Many babies develop temporary head shape irregularities that are completely normal. A cone-shaped head from vaginal delivery reshapes within days. Mild positional flattening (plagiocephaly) from sleeping on the back is very common and usually improves with repositioning and tummy time. However, head shape changes involving ridges, a persistently bulging fontanelle, or rapid head growth changes should be evaluated to rule out craniosynostosis.
Achondroplasia (Dwarfism) in Babies
Achondroplasia is the most common form of short-limbed dwarfism, affecting about 1 in 15,000 to 40,000 births. It is caused by a mutation in the FGFR3 gene and is usually apparent at birth with characteristic features including short limbs, a larger head, and a prominent forehead. Intelligence is normal. With monitoring for specific complications and supportive care, children with achondroplasia lead full, active, and independent lives.
Adenoid Hypertrophy and Breathing
Adenoids are lymphoid tissue located behind the nose that help fight infection in young children. When adenoids become enlarged (adenoid hypertrophy), they can block the nasal airway, causing chronic mouth breathing, snoring, nasal speech, and sleep-disordered breathing. Enlarged adenoids are most common between ages 2-7 and are a leading cause of obstructive sleep apnea in young children. Treatment ranges from watchful waiting and nasal steroids to surgical removal (adenoidectomy) if breathing or sleep is significantly affected.
How to Advocate for Your Child's Needs
You know your child better than anyone, and your observations matter. If you feel something is not right with your child's development or health, you have every right to ask questions, request evaluations, and seek second opinions. Advocating for your child is not being difficult - it is being a good parent.
Air Quality and Baby Health
Babies and young children are more vulnerable to air pollution than adults because they breathe faster, their lungs are still developing, and they spend more time close to the ground where some pollutants concentrate. The EPA recommends keeping babies indoors when the Air Quality Index (AQI) exceeds 100 (orange level). During wildfire smoke events, keep windows closed, use air purifiers with HEPA filters, and monitor your child for coughing, wheezing, or difficulty breathing. Long-term exposure to air pollution can affect lung development.
Altitude Sickness in Babies
Babies and toddlers can experience altitude sickness when traveling above 5,000-8,000 feet (1,500-2,500 meters). Symptoms are harder to recognize in infants because they cannot describe how they feel. Watch for unusual fussiness, poor feeding, disrupted sleep, vomiting, and fast breathing. Gradual ascent is the best prevention. Most pediatricians recommend avoiding sleeping at very high altitudes (above 8,000 feet) with infants when possible, and descending immediately if symptoms appear.
