Tummy, ears ,who knows

Today I took Reid to the urgent care because for the past 3 days he has been crying from pain in the middle of the night. He was grabbing at his ears and wasn't eating as much so I thought that maybe he had another ear infection. The doctor said he has some fluid in his ears but didn't see any infection so who knows. We switched him from soy to regular formula a couple weeks ago because we are trying to get WIC and WIC makes you have a drs note to get soy formula instead of regular formula...and we won't have insurance for a couple weeks until Steven's insurance from his new job kicks in...so i didn't want to have to pay a $100 copay just to get him a note....so we just switched him to see if the regular milk still bothered him like it did when he was younger so we wouldn't have to pay an extra $100 if Reid did okay on it...but I'm not sure. I'll give it the rest of this week and if he's still acting funny I'm going to switch him back to soy. So it could be his tummy hurting him...OR it could be teething...or it could be his lip. He was standing in his crib when I went to get him from his nap a few days ago and he got excited and smacked his jaw on the crib bar and must've bit his upper lip because there was blood everywhere :[ Scared me SOOO bad! I learned how to get blood out of clothes though. His lip was swollen that night but its not anymore so I have no idea if that's bothering him or not. I figure if he's still like this by the end of next week for sure (and he hasn't cut any teeth) we're definitely switching him back to soy. Well that's all for this post. I can ramble all day if i needed to lol.
