Does this sound like a baby that has some kind of problem with feeding?

If you rly worried about this just call the pediatrician and talk to him about all you Q's and concerns..he will be able to help you, and if he says the he needs to see him then make an appointment to see that Dr..Trust me if something turns out to be wrong then you will be glad you did but if not you will still be glad because you will be less worried about everything...
