My boy 7 month but still don't know how to how his bottle. I try giving him hold and drink himself but he will choke while drinking or he will just turn the bottle around and bite the whole bottle. When he grow older will he drink the bottle by himself?

He will of course hold the bottle himself in time to come. Some are fast, others may take a little more time and encouragement.

It takes time. Some baby tend to be a little lazier. so no worries. they eventually will learn to hold their own bottle

My son learned late too! I think he only knew when he's 11-12 months old, so ... 😅

yes definitely. mine only learnt how to hold at 1yo.
