Girls, hello ? My son is 2 months old, we're breastfeeding, when he eats formula, he spits out all the milk back, in huge amounts, I can't even hold it with a straw, even when I do, he makes burping and spits it out, 1 month we gained 1300, at 2 500 grams, now the weight is standing, the umbilical cord is normal, attachment is normal, tell me, could it be like that for anyone?
