On one of my previous posts I mentioned that we are using the calma nipple and a lot of moms came back saying they are bad. So here is my question. He has used the nipple now....about 3 days (only while I am at school from 9:00am-3:00pm) and it has not hindered his ability to breastfeed. So here is my question, should I stop using them? I understand that there are no nipples that are good for breastfed babies so does it really make a difference? I just want to do what is best for him, but I have no choice but to give him bottles Tuesday through Thursday from 9:00am-3:00pm.
