Hello Doctor, My younger daughter is 1 month 18 days old. For the last 2 weeks, she is spitting milk out. sometimes it is curdled milk and sometimes she vomits milk having frothy milk. I always give her a burp but still, she vomits. I told my doctor he said she is fine as she is gaining good weight(right now she is 4.6 kg). This whole thing disturbs her sleep. Is this a case of reflux? Please help me out, Doctor.
