My baby boy is 9 weeks old and has been breastfeeding only. For the first time I have to be away from my baby for a few hours this coming Saturday. I know he is gonna need to eat so I bought the Medela hand held pump. Since I'm going to be a stay at home Mom I really didn't need the electric one. I have never pumped and am hesitant with it. I have just heard too many stories of babies not wanting the breast anymore once they are introduced to a bottle. I was wondering if that is true because I don't want that to happen :-( Also I was wondering if I'm going to have to always pump after I pump this once this Saturday?
