Third time mom but first time being a pumping mom (formula other two times) I know the medela pump comes with bottles that you can attach the nipples to and feed that way but are those bottles bad for colic or any other issues? Would it be best to just stick to normal bottles? I hope my questions make sense! We really like MAM bottles but if just being able to feed out of bottles that you can pump into would be easier we would be willing to buy more of those. Also silly question but do medela bottles only hook to the medela pumps or can I use them with the spectra pump??
