Anyone else struggling?

My little dude is pushing everyone's buttons. He room shares which has never been an issue until bow and he's jumping into his brother's crib whose one and asleep and waking him up. Naptimes are nonexistent but he needs sleep. Hes a hot mess by the afternoon. Telling him to do anything results in a fight. The melt downs are exhausting. He goes to a Christian Base Preschool 2 mornings a week and he told me today he's been in timeout there. One night a week he's in skating and he wont do as he's asked by his teacher there my husband had pull him off the ice this week. He's in Swimming and same he wouldn't follow directions and the other children do. I had to pull him out of the pool for a safety concern. Im worried there is more going on with him. My background is in special ed and I'm seeing focusing issues, melt downs, and he is biting his finger nails and holes in shirts. He's so smart has friends I'm just trying to figure out how much is age-appropriate or is this my strong willed first born going to teach me lessons I didn't learn as a teacher.
