She, sorry. I have a boy, I'm stuck on "he" things. Sorry sorry. But yeah, each kid learns at a different rate.

@kimberlyyyy, ok. that's kinda what I was thinking. she is doing a lot of other things, saying momma & daddy perfectly, almost crawling, rolling all over the place. I guess she is just doing things a lil backwards. thanks

My friend texted me asking the same thing. My son was 7 months when he sat up on his own but each kid is different. You'll blink and he'll do it. If you're concerned talk to his doctor but it's okay for them to do things on their own time.
