Baby is starting to get into things and may get hold of something you don't want him to have. Since everything he picks up goes into his mouth, it's time to think about safety.
Breast milk or iron-fortified formula is still your baby's main food. But you can now start adding some semi-solid foods to baby's diet.
As your baby reaches 5 and 6 months, watch how he reacts when things disappear from view. Does baby lean over to look for things he dropped? Does baby put a toy down and go right back to it later?
Now that you've had a few months to get to know your baby, you're probably noticing she has a personality all her own. The part of personality your baby was born with is called temperament.
Baby has lots of energy! Baby seems to be moving all day when she isn't asleep. Many 5-month-olds can move around by rolling or wriggling. You'll need extra patience to keep up with her.
