Developmental Milestones

0-1 Months

• The CDC has not identified milestones for this age and area of development. As a parent, you know your child best. If you think there could be a problem with the way your child plays, learns, speaks, acts, and moves talk to your child’s doctor and share your concerns. 

2-4 Months

• At this age, infants sleep on and off during the day and night. Most infants sleep for 14-17 hours in every 24 hours.

5-6 Months

• Most infants this age sleep 12 to 16 hours at night and, may wake up for a feeding or two. They also nap for three to five hours a day, spaced between two or three naps.

Ideas for Learning and Growth

• Respond positively to your baby. Act excited, smile, and talk to him when he makes sounds. This teaches him to take turns “talking” back and forth in conversation.
• Talk, read, and sing to your baby to help her develop and understand language.
• Spend time cuddling and holding your baby. This will help him feel safe and cared for. You will not spoil your baby by holding or responding to him.
• Being responsive to your baby helps him learn and grow. Limiting your screen time when you are with your baby helps you be responsive.
• Learn to notice and respond to your baby’s signals to know what she’s feeling and needs. You will feel good and your baby will feel safe and loved. For example, is she trying to “play” with you by making sounds and looking at you, or is she turning her head away, yawning, or becoming fussy because she needs a break?
• If your baby seems sleepy, place them on their back in a safe sleep area (firm mattress with no blankets, pillows, bumper pads, or toys).
• Have routines for sleeping and feeding. This will help your baby begin to learn what to expect.

Concerns

• Is there anything your infant does or does not do that concerns you?
• Has your infant lost any skills he/she once had?
• Does your infant have any special healthcare needs or was he/she born prematurely?

If your infant is not meeting one or more milestones, has lost skills he or she once had, or you have other concerns, act early. Talk with your infant’s doctor, share your concerns, and ask about a developmental screening.

If you or the doctor are still concerned:

• Ask for a referral to a specialist who can evaluate your infant more.
• If the evaluation still shows concerns call your state Early Intervention program to find out if your infant can get services to help. Learn more and find the number at Missouri First Steps Program.
