Infant Development: 3rd Month Milestones

By now your baby is probably starting to become more alert as they are growing out of the newborn phase. You may notice them becoming more social and interactive with you. Here’s a look at a some of the things your baby might be doing during his 3rd month in infant development.

  • While holding them in a standing position, may begin to bear some weight on both legsDSCN2719
  • May be able to lift head and shoulders between 45-90 degrees while on stomach
  • Able to hold objects when given to them
  • Laugh out loud, squeal, or babble
  • Smiles in response to familiar faces and verbalizes in some way to them


Other Things Your Baby May Be Doing

Some, not all, babies develop a little faster than others and may be showing some of the following skills:

  • Hold head steady when sitting or in upright position
  • Roll over one way
  • Make vowel-consonant sounds such as ‘ah-goo’
  • Reach for an object
  • Make wet, razzy sounds

Most babies will not have a well-baby check up at 3 months, unless it’s a follow-up for a previous condition. If you have any concerns regarding your baby’s health or development do not hesitate to call your doctor.

Transitioning to the Nursery

Most parents choose to have their babies in their room during the first few weeks due to the frequent night feedings and rocking sessions. If your baby has slept in his own room since birth than this does not apply. However, if your baby has been sharing a room with you, now is the time to get him used to sleeping separate from mommy and daddy. Trust me on this, because I know first-hand it is a hard habit to break.

Most babies will outgrow the physiological need for frequent night feedings by the time they reach 3 months (some sooner, others a little later). Once they reach this stage it is crucial to begin transitioning baby to their own room. Why? If your baby gets into the habit of sharing a room you will encounter a number of issues:

Less sleep for you and baby – once babies get accustomed to particular habits, it is difficult to change. It is normal for babies to occasionally whimper at night, but if you go over and pick him up every time it will be difficult for him to overcome the security of being in mom’s arms. Furthermore, most babies by this age are capable of sleeping through the night so if you are still giving night feedings your baby’s tummy will have that sense of emptiness prompting baby to feel the need to eat at that particular time (such as 3am!) even though it is sufficiently full enough to last all night.

Less Romance– If you are still sharing a room with baby, even though you are certain he’s asleep it can still compromise your love-life in the bedroom. I won’t divulge into further reasons of how this is compromised especially if you are co-sleeping, but you get the general idea.

Problems Adjusting Later– This is the problem we faced. I suppose I did things backwards, but with my first child I had no problem getting her used to sleeping in her own crib and now her toddler bed. My son, however, was much more difficult to train. He had become used to sleeping in our room in his infant sleeper, so when the time came (at 6 months, yes I know) to put him in his  crib it was very difficult. We spent many restless nights, all of us, because he would not adjust to the open space of his crib as opposed to the closeness of his sleeper, or mom’s arms. For some families, especially those who live in small homes or apartments, this is not an option. For others with multiple children, the baby may have to share a room with another sibling. Ultimately you do what works for you and your family, even if it means sacrificing your bedroom.

Keep in mind that babies will develop at their own rate and may do some or all of the above listed developmental skills. If you notice your baby hasn’t achieved any of these skills, check with your doctor. It may be perfectly normal, though in some cases a delay in infant development could be an indication of a medical problem.
