Milestones?

Nikole
My 11 month old can do a lot of things she said professional crawler she recently started standing up in her crib and with objects. She claps she waves she says mama dada she plays peek-a-boo although I know she's a little behind physically she does a lot the one thing that I can't get her to do was hold her bottle yet. I've tried sippy cups with handles and she doesn't like them she only likes her dr. Brown's bottles. She loves to drink at a baby cups with straws but surely I can't give her her formula that way right? He's not the best either solids anyway she has no teeth yet and doesn't have much interest in solids. Is this normal?
