Girls, hello, I recently gave birth, my little one is already a week old, but I've run into this problem recently. She's not taking my breast, even though she eats milk, in the hospital they were feeding her formula, we got discharged, the baby can't poop all day, from that she can't sleep and gets fussy, I don't know what to do, my belly hurts, in the hospital they gave her formula + supplemented with cow's milk, only just left the hospital today, in the hospital couldn't poop for a whole day, now she can't sleep, she fusses, then falls asleep, then wakes up, I massage her tummy, nothing works, please
