Not in place of breast milk but in addition to? My supply is totally regulated to her so I have a hard time getting extra milk to pump. She doesn't get many bottles but DH and I switch nights. Sometimes she gets up 2xs/night/. Sometimes it will be 1. I only have enough milk for 1 bottle/night so if she gets up more than one time he has to bring her in to me which screws up the whole point of switching nights. Anyway, it's not like she is waking up because she is hungry when it's the 2nd time since she only does it occasionally. She will be 1 in about 6 weeks. She has had yogurt and a few sneaks of ice cream so she has been exposed to cow's milk.
