My 3 month old son has gotten to an increasing point of crying during or after feeding. He wasn't like this before he went over to a realitive house for one weekend cause some other family came from out of town to see him and they wanted to give me some peace. That was 3 weeks ago. He started crying during feedings after that when we tried to burl so I just stop burping him until after. This past weekend I let him go to the same relative for 3 nights since I had to go out of town. Since he's tback with me he crys like crazy after the bottle is empty. He'll burp aftwards but still cry. After both visits I've found 2 bottle nipples that look like they were cut but the relative says they cracked. I'm starting to question if someone haz been giving him something else when I'm not around even though I've said he was to young for cereal with my son's doctor backing me on this. Not sure what to do now cause I'm facing two issues: a crying baby that I can't sooth for anything after eating and a possible lying family member.
