Developmental Milestones to Watch for: First 6 months

There has been nothing in life I have enjoyed as much as I have enjoyed being a mom the last 6 months. Here are milestones to watch for at two, four, and six months.

Baby sitting in front of six heart shaped balloonsI have been a mom now for half a year. Magnolia turned 6 months old earlier this week and what a joy she has been. She is a happy girl and brings happiness to all that know her. It is so fun to watch her grow, learn, and develop into an intelligent little lady. Each month babies hit new milestones to show they are developing properly.

These are developmental milestones to watch for at each age. All children learn and develop at different rates. There may be some things that your child does sooner and there are some they may do late. Talk to your doctor and they will help you to know what a concern is and what isn’t.

2 Month Milestones:

At 2 months of age, you will notice your baby will begin to smile at people, briefly calm self, and tries to look at parent.

Your baby will coo and turn head toward sounds.

They will start paying attention to faces, follow things with eyes, recognize people at a distance, and acting bored by crying or fussing if activity doesn’t change.

Tummy time is important for all babies to build neck strength. Your baby can hold head up and begin to push up during tummy time. Their movements with their arms and legs will be smoother.

The CDC says to speak with your doctor if you child doesn’t respond to loud sounds, doesn’t watch things as they move, doesn’t smile at people, doesn’t bring hands to mouth, or cant hold head up when pushing up during tummy time.

4 Month Milestones:

At 4 months of age, your baby will smile spontaneously, especially at people. Your child might like to play with people and may start to cry when the play stops. They will begin to copy some movements and facial expressions.

At this stage, you will notice your baby babbling. They will babble with expression and may copy the sound they hear. Your baby will cry in different ways to show hunger, pain, or being tired.

Your child will let you know if they are happy or sad and will respond to affection. Babies at this age will begin to use hands and eyes together like seeing a toy then reaching for toys with one hand. 4-month-old babies follow movement with eyes from side to side. They watch faces closely and recognize familiar people and things at a distance.

Babies will hold head steady and unsupported. They may be able to roll over from tummy to back. They can hold a toy and shake it and hit at dangling toys. Babies at this stage will bring hands to mouth and explore other objects by bringing them to their mouths.

According to the CDC, you should talk to your child’s doctor if at 4 months old they don’t watch things as they move, doesn’t smile at people, or doesn’t coo/make sounds. If your baby can’t hold head steady, bring things to mouth, or doesn’t push down with legs when feet are placed on a hard surface, you should tell your doctor. Lastly, if your baby has trouble moving one or both eyes in all directions, let your doctor know.  

6 Month Milestones:

At 6 months of age, your baby will know familiar faces and will know if someone is a stranger. Babies at this age like to play with others. They can respond to others’ emotions and often will seem happy. They like to look at their face in a mirror.

6-month-old will respond to sounds by making/mimicking sounds. When they babble, they will make vowel sounds and begin to use constant sounds. Likes taking turns with parents while making sounds. An important part of developing language is talking to your baby and reading them books. Babies can respond to name and make sounds to show joy or displeasure.

Your child at this stage will bring things to mouth to explore. They will look around at things near to them, show curiosity about things and try to get to things out of their reach. When holding things, they will be able to pass things back and forth from one hand to the other.

Babies will roll over in both directions, front to back and back to front. They will begin to sit without support. While they stand, they will support weight on legs and might bounce. Babies will rock back and forth, sometimes crawling backward before moving forward.

The CDC says you should talk to your child’s doctor if they don’t try to get things that are in reach. If your baby doesn’t show affection for caregivers, doesn’t laugh or squeal, or doesn’t respond to sounds, you should talk to your doctor. Another reason to contact your doctor, if you baby has difficulty getting things to their moth, doesn’t make vowel sounds, or doesn’t roll over in either direction. Lastly, a sign to contact your doctor is if you baby seems stiff with tight muscles or seems very floppy like a rag doll.

All babies hit developmental milestones at different rates; you shouldn’t compare your baby to another, even if it’s one of your other children. Stay in contact with your child’s doctor and communicate any concerns you have at any time.
