About this assessment
See how your child’s milestones compare
Answer a few questions about your child’s age and current skills to get guidance tailored to common developmental milestone checklists for babies, toddlers, and children.
01
How to use a developmental milestone checklist
A developmental milestone checklist by age can help you notice patterns in how children grow, communicate, move, play, and interact. These checklists are most useful as a guide, not a scorecard. Some children reach milestones a little earlier or later than others, but a checklist can help you spot strengths, track changes over time, and identify areas that may deserve a closer look with your pediatrician or an early childhood professional.
02
What milestone checklists usually cover
Toddlers
A toddler developmental milestone checklist may look at walking, climbing, first words, following simple directions, pretend play, pointing, and social interaction.
Older infants and young children
A child developmental milestones checklist often includes language growth, fine motor skills, problem-solving, play skills, emotional regulation, and everyday independence.
03
Signs a checklist can be especially helpful
You want an age-by-age view
If you’ve searched for developmental milestones by age chart information, a checklist can organize expectations into a simpler format that is easier to review.
You’ve noticed uneven progress
Your child may be doing well in one area but lagging in another, such as strong motor skills with fewer words, or good language with social concerns.
You’re unsure whether to follow up
A developmental screening milestone checklist can help you decide whether your observations are worth discussing at your child’s next checkup or sooner.
04
When to seek extra support
If your child has lost skills they once had, is not meeting several milestones in a row, or you have a strong gut feeling that something is off, it’s a good idea to talk with your pediatrician. Developmental concerns are easier to address when noticed early. A checklist cannot diagnose a delay, but it can help you describe what you’re seeing and prepare for a more informed conversation.

Frequently asked questions
What is a developmental milestone checklist by age?
It is a guide that lists common skills children often develop at different ages. It may include movement, language, social interaction, play, and problem-solving milestones.
Is a baby developmental milestone checklist the same as a diagnosis?
No. A checklist helps you observe and organize what your child is doing. It does not diagnose a developmental delay or condition, but it can help you decide whether to seek professional input.
What developmental milestones should my child have right now?
That depends on your child’s age and the area of development you’re looking at. Milestones are usually reviewed by age range, which is why an age-by-age developmental milestones checklist can be helpful.
When should I worry about missed milestones?
It is worth following up if your child is missing several expected skills, seems much later than peers in one or more areas, or has lost abilities they previously showed. Regression should always be discussed with a healthcare professional.
How is a toddler developmental milestone checklist different from an infant checklist?
Infant checklists focus more on early motor, sensory, and social responses. Toddler checklists usually include walking, language growth, following directions, pretend play, and early independence.
