Hello! When my LO turns 4 weeks next week, we plan on introducing her to a bottle once or twice a day. For two reasons...so my DH can join in on the feeding and to prepare her for when I return to work. I currently BF exclusively and when she feeds, it is off one breast per feeding. So, can someone please let me know... 1. How often should I pump or when should I? 2. How many ounces per bottle should she be fed (we don't know her current weight)? 3. What is the best way to know that both the fore milk and the hind milk are in the bottle?
