When do?

When do babies usually start to hold their head up?

It varies.

DD did at 2 weeks, not a joke.
DS did at around a month.

Okay bc my little girl started to at 2 weeks also an i kinda thought that was early! Lol i was so very proud of her(:

Both Ethan and Adrian did at 3 weeks - a month old.

Quoting Mrs. Dexter Morgan:" It varies. DD did at 2 weeks, not a joke. DS did at around a month."

DS was 2-3 weeks old.
