I know, it sounds like an easy ?, but, just thought I would ask here rather than google! I am planning on breastfeeding...however, would like once a routine is somewhat established, to express and have Hubby help a bit :) I am planning on using NUK glass bottles...they have two sizes, the newborne (presumably, smaller size!) and the larger size up! How many do you go through if say you are breastfeeding the majority of the time and say Hubby helps out occasionally? Not sure if this question even makes sense, as I have never done this before! Any tips appreciated :) Thank you!
