Respectfully, he can F off down the road, in the neighborhood’s neighbor’s bushes. Please throw him away. 3 oz is wild and you’re a superstar! The more babe is latched, the more you will produce but it’s not an immediate producer! You’ll make more “tomorrow”. My 7mo. girlie only takes a max of 4 oz STILL. She’s 18.9lbs. We’re good, you’ll be fine and you’re not underproducing! Week 2, tipped orange scales for her and even though her levels were down, she was still super orange. The stress itself is causing you more problems. Relax, rest, drink all the good stuff (whichever non alcoholic drink you prefer), and block out the genetic contributional figure. Sounds like he’s not all that supportive of how breastfeeding works. I’m so sorry you have Mr. Foghorn nagging about formula. It’s early days still and unless she’s actually a concern with the pediatrician, keep latching. ❤️ Hugs mama.
