I started my son at 3 months and at 4 months was completely off of it. If they take it they take it not like we force them to drink out of it.

I just seen the pic girl he is fine he isn't struggling or nothing.my oldest wouldn't drink a bottle at all at 5months by 6 months she was drinkin a sippy all the time. I see it this way learn early know more. My daughter learned everything before the recommended age and she is smart as hell

I not bother me I just want to know other opinions if I was or it ok. I know I had other kiddos but I didn’t use the sippy until one

People will always have opinions.
As long as he’s getting his recommended amount of milk then it’s great your introducing it now. It gets hot here in NV so we offer water in the sippy at 5 months in between bottle feedings.
I would talk to his pediatrician if it’s bothering you that much.

We are just starting the sippy cup and he seems to do well and he a pacifier baby so if I can get rid of the bottle then that one less habit to worry about

I saw the pic you posted . It seems like his doing just fine with the sippy cup . I think you should get rid of the bottle and introduce the sippy cup more. By the time he turns one his probably going to do good drinking from a cup . It’s better for his teeth so ... yup your doing fine 😊
