Unfortunately I have to second what @royce_ivy said. Feeding a baby like that is bad news because of choking potential and ear infections. Im NOT trying to tell you how to parent, but I have had four babies, one on the way...Ive learned a lot over the years.
If u don't mind me saying ...u know that's how babies can catch an ear infection right...he's way too young to be laid flat like that drinking a bottle
i agree with @royce_ivy @sarahemccormick
