Baby A when I prop her up can hold her head up straight. Baby B (my bigger girl) seems to always let her head fall to one side. I know we arent supposed to compare, but is this normal? Baby A is also a lot better at holding her head up during tummy time.
Here is a pic to see what I'm talking about.
