Developmental Delay and Milestones

What is Developmental Delay?

Developmental Delay is when your child is not doing certain things that kids usually do at their age.

There are different kinds of development, and different milestones: things a child usually can do at a certain age.

Kids learn things at different ages, so there is a big range of what is "normal". But an evaluation can tell if your child may need some help to catch up.

Here are some examples of different kinds of milestones:

• Physical things like holding up their head at 3 months old, or sitting up at 9 months.

• Cognitive (thinking and learning) skills, like imitating a movement at 1 year old, or knowing some body parts at age 2.

• Communication skills, like saying "ba-ba-ba-ba"at 9 months, or waving "bye-bye" at age 1.

• Social and Emotional skills, like laughing at 6 months, or showing affection for caregivers at age 1.

• Adaptive or self-help skills like eating, dressing or using the bathroom
