if you can't, tell her in the face that you will have enough milk if she is more supportive.
anyway, if you dont want to give FM, why keep FM at home?
Yes, they should be encouraging you. But most CLs are old school who were brainwashed and think FM is better. only poor people drink breast milk. and they are seriously worried that ya baby is starving.
as for baby walking up less than an hour, are you latching correct?
Get some1 who has breastfed successfully to check? or see a Lactation Consultant to make sure.
