hi my name is Rizwan and my son Umar has completed 3 weeks now. The problem is his belly button is still bleeding when i change his diaper each time i see some blood on it, his Dr. has put some alcohal when he was 2 weeks old but it didnt work i heard about mustard oil but i am little bit confused that weather i should apply it or not as little ones are too sensitive help me please suggest me what to do and one more thing i need to discuss that is it possible that it is not recovering because my wife after feeding help him to burp in sitting position may be this position put some pressure on belly button, am i right or wrong?
