My son is now a month old and I still haven't been able to get my milk supply up. I've been pumping but I've never been able to pump more than 3oz total and he eats 4oz. I wanna breastfeed so badly, but he isn't latching on because he's too used to the silicone nipples. How can I possibly get my supply up so I can give breastfeeding a try again? I tried the mothers milk tea but it just made it go down. Oatmeal isn't really helping either, so I just need some tips that have actually seemed to work wit you guys. I'm really starting to get desperate. I know it doesn't work for everyone but I wanna at least be at peace knowing I tried everything. So I need all the tips I can get 😅
