How old is a baby born in March 2024?

A baby born in March 2024 is currently 4–8 weeks old.

These babies are considered newborns. They sleep a lot, they wake every 2–4 hours to feed, they can't support their heads, and they can't see very well. They also make a lot of jerky movements.

Although some of these children have passed the one-month milestone, their age is still measured in weeks due to their rapid development.
