My poor little boy!

So monday morning my little boy has this weird mark on his cheek. We don't know what it is but it goes away. Well later that night i was getting him ready for bed and his left upper arm is covered with this red mark and two white spots in the middle. It looks like a bad burn but there was no way it was plus it didn't seem to bother him. Ben and i called the doctor on call and she said it was probably a bug bite and to give him some benedryl. So the next morning when he woke up it was on his other cheek. Very weird but it went away. He woke up from his nap and it was covering both cheeks and ears as well as the lower part of his arm. I called the doctor they told me to come in. I took these pictures since they kept going away. The doctor had to look at the pictures (which he thought was awesome that i had done(yeah i am awesome)) and said it was hives. He is allergic to something, food or clothing and i had to play sherlock holmes to find it. Well it kept getting worse i didn't take anymore pictures but it at one point covered his thighs and bum. It looked horrible, luckily it didn't seem to bother him. On top of all this he is getting a new tooth and is mr grouchy. Oh and i think he has a cold since snot is dripping down his nose plus he's stuffed up. Anyway i think i have found the culprit, he was fine on thurs then i gave him a burrtio (he loves them and he eats it so i fed him them alot) and lo and behold that night there is hives!!! So i guess he is allergic to something in the burritos, which kind of sucks cause now i can't feed them to him but i have found the cause of the hives. Now the cold and tooth need to be done!!!
