Best quick acting supplements

Co

That I can order off amazon? No fenugreek. I need to get my supply up fast, my baby is not gaining enough weight 😢 he has lots of wet/dirty diapers but ped wants us back next week to weigh him again. I’m drinking water and Body armor drinks and eating oatmeal

I fed him for 20 min on each side with a break between and he still acted hungry so I warmed up 2 oz from my freezer and he sucked it down so fast and now is quiet again 😭 I feel like the worst mom
