Developmental milestones are more like waypoints marking the course of typical development than they are fixed points that all kids hit. Some babies may reach 3-month milestones early while future milestones late. Some babies may skip certain milestones altogether. Taking this into account should help ease unnecessary anxieties parents might have about their child “making progress” in their 3-month milestones. If parents look at their 3-month-old as a whole person instead of set of skills that need to be marked off a list, everyone benefits.
In the third month of your baby’s life, growing strength and social interactions are on the menu. If you hadn’t seen their personality blossoming in month two, you should see them start to display their joy, boredom, and frustration in the coming weeks. With personality and strength comes the ability to indulge their curiosity. So this month’s main infant milestones are about reaching out to touch someone (or something).
3-Month Milestone #1: Baby Should Be More Social
Your baby might have been slow to smile in the second month, but as the third month progresses, parents should see their baby flash a smile in response to play and activity. Along with that smile should come a change in facial expressions along with a bit of babble. They won’t be saying momma or dada yet, but you may hear some breathy gahs, ohs, guhs, and oos. The babble may be subtle or pronounced. It will definitely be pretty slobbery.
If you’re lucky, you may be able to coax a belly laugh from your kid while you play. On the other hand, your 3-month-old baby may start crying when play is done. These are all great signs of on-point development, but they also require a little coaxing from parents. Playing with baby (at this point, this means making different sounds and facial expressions) is essential for the kid. Without this interaction, babies can’t practice their mimicry and may be a bit slower to gain their social skills.
Red Flags: Parents need to leave room for babies who are hesitant to offer social responses, but there is a difference between a baby who appears reluctant or slow to react to parents and a baby that appears incapable of a social response. The red flag here is more about the absence of a set of behaviors. A baby who doesn’t laugh or coo, but does smile, is likely just taking their time. The same goes for a baby that looks interested in their parent, coos and babbles, but doesn’t smile. You may simply want to take some time to see if anything changes in the coming weeks. But a baby that seems completely disinterested, does not babble, look at parents or smile, may need to see their pediatrician sooner rather than later. This could be a sign of any number of neurological disorders that can be addressed with early intervention.
What You Shouldn’t Stress About: At this age, it’s normal for babies to fuss and cry, particularly when they are bored, or something they enjoy has been taken away. They may also cry when they are put down. This is normal. If you suspect there is a deeper issue, there’s no harm in talking to your pediatrician.
3-Month Milestone #2: Baby Should Start Reaching For and Grasping Objects
At three-months-old, the spark of play is lit. Babies should be able to reach and grasp for things they are curious about, and may start to explore cause an effect by bopping things that make noise when grasped or jostled. Granted, this play is primitive and might look more accidental than intentional. Still, embedded in the play is proof that on a physical level things are clicking along. A newborn who can play in these very basic ways is showing that they can see and track objects and coordinate their limbs. A baby that repeatedly bops or kicks of an object that makes sound, shows that they are developing muscle strength and that they can respond to auditory cues.
Red Flags: Babies who seem to be unable to reach and grasp, or who do not take any interest in loud noises may be experiencing nervous system issues. The same goes for babies that appear to tense in their limbs or too floppy. An inability to lift their head during tunny time over the next four weeks should be brought to the attention of your pediatrician.
What You Shouldn’t Stress About: Babies at 3-months-old will grab and hold just about anything that they can get their hands on. So if they are pulling hair, beards, or their own private parts, it’s not an issue. It’s just something that happens.
Non-Milestone Moments In Baby’s Third Month
Newborn sleep starts to normalize over the next few weeks. And as babies are able to bring hands to their mouths and suck their fists, they should be learning to self soothe. Also, at three months, as babies start learning to roll over, their risk of SIDS begins to decline. All of this means that babies can move into their own nurseries and parents can begin thinking about sleep training. If you haven’t thought about how you plan to do this, now is the time for research.
