Another rough night for aaron

He went to bed around 9:30 and was up at 3 am until 6 am. We dont let him down to play or anything he just fights sleep that long. He gave him ibuprofen and a cup of milk, he just wasnt intrested in sleeping like mommy and daddy were. I dont know what i am doing wrong. Maybe its just him teething, but it looks like once the ibuprofen kicked in he would go back to sleep.
