help! losing weight from breastfeeding

so normally my weight is about 125-130. right now i weigh 109. my weight is just steadily going down & idk what to do. does anyone else have this problem? i eat enough throughout the day & i’ve even been eating bigger meals & im still losing. at this point i’m losing about a pound or more a week. i don’t want to stop breastfeeding but i feel like i’ll have to. on top of that my girl will not take any bottles. so it’s gonna be such a hand transition. i just don’t know what to do. any advice is appreciated
