Girls, it's a cry from my heart!!! My son is 4 months old, he feeds from the breast, burps, then asks again, I'm already exhausted, he's constantly hanging on the breast, I can't do anything, I still need to pay attention to the older one ?We have intracranial pressure, because of this after each feeding he burps, tell me, could anyone have had this? I want to try giving him formula, but from the formula it seems like he will also burp, but I don't know if he will ask for more later ?
