Girls, hello! The baby will be three months old soon, has been constipated for two days now, restless, feeds immediately after breastfeeding and then poops, sleeps poorly, turns constantly and cries, there's a burp in the belly, sometimes it's flatulence, the tummy is inflated. There were colic, but now it seems worse. Went to the hospital, they prescribe the same drops, prescribed Lactifil too, it doesn't help.
