Neither one of my twins care much for tummy time, and my daughter actually down right hates it. Screams and cries the whole time we do it, so we don't do it very often. My son will do it for a few minutes but then he's over it. He's come close to rolling over a few time and has a really strong neck and back. He actually sits up in his Bumbo seat perfect and he really enjoys that. But I'm not sure how well he should be doing with pushing himself up on his elbows. He doesn't seem to do that much when he's on his tummy.
My daughter is a very lazy baby. She's never come close to rolling over and doesn't even seem interested in trying. She hates tummy time, she just barely lifts her head and turns it from side to side occasionally. She is getting better at holding her head up but still flops it around a lot. And she does ok in her Bumbo seat for a few minutes but then starts to slump to one side.
I know they are two different babies that will develope at different rates but it is really hard not to compare them, especially when I have no other children to compare them to. Any thoughts or advice? Thanks.
