Dr my question is when to stop using vent in Dr brown bottles and which bottles are good for introducing cow milk to baby ?Suggestions from experienced moms would be really appreciated.

A. Hi use a straw sipper To introduce cows milk to your child because that way your child will at least be used to be a better thing .. rather then going for a feeding bottle so you can definitely start with that and honestly you are using some branded eating what is you should stop using them now try to switch to what I am suggesting
