I think you are doing amazing 💐
Of course these men aren’t twats from the start. They know what they’re doing. Pregnancy is the classic time for abuse to ramp up and their true colours to come out, because you’re ‘trapped’ then.
Except you’re not OP - you can absolutely choose whether or not you stay with this man. But that’s maybe not a decision for today.
Today, you need to just get through it. And you will. You have this amazing new baby, a whole brand new person who will be your best friend forever. It will all be fine in the end, there will just be a tricky time for now. It’s a shame, because it shouldn’t be a tricky time, but it is. It will pass though and you will come out stronger.
Feeding - cluster feeding is absolutely a thing. I am a midwife and also BF 3 babies. I have oversupply of milk and even I couldn’t express, it’s no indicator of how much milk you have. Ignore the twat in the next room and just settle yourself on the sofa with snacks, baby and a box set on tv.
7% weight loss is great to you are doing it right!
If it is painful or baby is not settling to a good feed ever, ask the MW for help.
You will get through this, but you will never forgive him and nor should you. Write it down to remind you how he behaved later on, because he will absolutely gaslight you and say it was baby brain fog and actually he did loads🙄
Good luck lovely, keep posting 💐
