Hi, Gemma,

Congratulations, and good on you. What you are describing is very common in a breastfed baby. Do you know why the dr suggested comp feeding from day 2? At day two your milk wouln't be coming in yet, so she would not really be expecting any quantity from you, and would have reserves of brown fat that she would be using up. Did you feel that your milk came in? Any fullness? Any feelings of letdow? Milk dripping from the other breast? How big was she when she was born? Have you had her weighed since her birth?
It sounds like your LC is giving you good advice, so stick with her! How much formula are you giving your baby now? Many mothers of week old babies are in just the position you are - breast reduction or not! But she won't learn to breastfeed by drinking from a bottle. So try to get her to feed from the breast as much as possible. Have plenty of skin to skin contact. I wouldn't necessarily assume that your milk supply is low.
Looking forward to hearing from you again

Regards
Barb
