Are Your Children Meeting All Their Developmental Milestones? Red Flags by Age

Do you find yourself constantly assessing if your children are meeting all of their developmental milestones? Why isn’t he walking? Shouldn’t he be talking more? Should he be able to hold a crayon? Draw a circle?


Do you compare your children’s development to other kids their age? Even if we don’t want to do this – it is sometimes hard to control.

Do you worry about whether your children are meeting their developmental milestones. Here is a great reference listed by age.

Well stop guessing if your children are meeting their developmental milestones! I invited Physical Therapist and Early Intervention Specialist, Trisha Roberts to help us understand what red flags we should be looking for by age.


Children develop at their own rate, but there are normative charts for the average time frame for major developmental milestones and achievements.


If a child is significantly outside of the normal range, it is considered a red flag. The following are red flags by age. If your child is exhibiting some of these red flags, consult your pediatrician and/or get an evaluation from an Early Intervention Specialist.

NOTE: If children were born prematurely, they will most likely be slower in acquiring their developmental milestones, but the progression should follow the normal sequence, not necessarily the same age range.

What Should I do if my child is displaying developmental red flags?

Early intervention in the form of Physical Therapy, Speech and Language Therapy and Occupational Therapy can dramatically improve a child’s development. The sooner treatment starts, the better the prognosis and outcome. The let’s wait and see approach is not best in these situations. If a parent is concerned and has noted several red flags, they should seek an evaluation by their child’s pediatrician or an Early Intervention Specialist.

Therapy with an infant, baby or young child can significantly improve that child’s overall function and development. Early Intervention Specialists will use unique toys and activities that will engage your child in play and promote development. Your therapist will give you exercises, activities and suggestions that you can use to help your child. Regardless of the cause or severity of a problem, the goal of Early Intervention Therapists is to maximize the potential of each child!
