Kids Home > 5-Month-Old Baby (23 Weeks)

When your baby is around 5 months old, she will have a definite preference to you over anyone else. This development, also known as separation anxiety, comes from a preference for you and a dislike to new faces. This may also be an important time to review your 23-week-old baby's upcoming vaccinations. At her 6-month checkup, your baby will receive the Hib vaccine, to prevent bacterial meningitis.

You and Your Baby at 23 Weeks

Babies at this age are jumping from milestone to milestone almost daily. They are beginning to learn how to move themselves around, even if it is just to roll over or shimmy a few inches.
Five-month-old babies are starting to make a few more sounds and will be in awe over the effect their vocalizations have on you.

Major Developments for a 5-Month-Old Infant

This is such a great age because your baby is learning and growing right before your eyes, while developing a like and dislike for certain things. While he has always favored your touch and has been comforted by your smell, more than ever he will now demonstrate a definite preference to you over all else (whether convenient or not).
There are a few things playing into this development. There is the distinct preference for you, but also a new and growing dislike to new faces. This is sometimes referred to as separation anxiety.
Another development for an infant of this age is the increasing number of ways he has learned to communicate his needs to you. Crying for everything is old hat these days. There are uh-ohs, giggles, and saliva bubbles to blow for now.
The first true words are likely to be months away, but that doesn't mean that your little one isn't trying to tell you many things now. Just wait, in time, "Mommy's ears will be tired!"
