Breastfeeding/Husband ?s

Ladies I need some advice. I am bf and pumping on the days I don't have her at work with me. My husband keeps telling me I'm not giving her enough milk! He says she will drink a full bottle when he's home with her (10oz). She's 3 months old, gaining weight, plenty dorty diapers. Idk what to do! I think she geets enough from me but how do I convince him?! Today at lunch I bf her and when I was leaving he asked me to get a bottle ready because she was still hungry. It's starting to really hurt my feelings!
