Twins are usually going to be like day and night. Nothing to worry about at all. Ita a common thing.

I've heard nothing but horror stories of base doctors. Ugggg. Yeah. I would highly recommend seeing someone else. Someone who knows what there talking about. && why the F would someone give your babies cough meds?! For what?! That's insane anyway even if they weren't early.

@kimberlyyyy thank you. They have an apt on the Air Force base because the pediatrician off base doesn't let me talk or finish sentences and he gave Xaiden cough medicine that he isn't even allowed to take. So, I think I'm just gonna keep taking them on base. Lol

With them being young it's hard to tell. I would definitely bring it up with their pediatrician next time you go in. If it does seem to be concerning there are early intervention programs for preemie's that help them reach milestones. It could also be lazyness though. They're still young. Just keep an eye on them both, maybe make notes of things that concern you about them.
