My son has been burping a lot. I took him to his ped who said he was too young for allergy testing. I found out that this was not the case and I am taking him to an allergiest next week. I am trying to find as much info out as I can so I can ask the doctor intelligent questions that would help my son. He seems to be burping a lot and his poop seems very loose and smells like natural gas or gasoline. I know natural gas doesn't really have a smell so it smells like the stuff they put into gas so that it would smell. His weight is fine, so my ped said not to worry but I am worried that he is hurting. He also poops a lot, about three times a day. He is going to be 3 in jan 2014. I didn't think three times a day was normal for a 21/2 year old. The smell has me concerned. SO I am trying to figure out what I should be asking the doctor and whether we should also be seeing as gasternol doc.
