Small edit You know your 3 year old has OCD when...
He wakes up screaming at 5 am because his "blankie is broken" which means is not completely covering his bed evenly!
Once awake he can't go back to sleep until you fix his brothers pillow because the ninja turtles are facing the wrong way!
He has to close every door or gate that's open!
He needs a new napkin or baby wipe every time he wipes his hands!
He can't get even a drop of water on his clothes without needing to change them.
Washes his hands constantly with soap & water.
Puts things exactly in their place ALWAYS! Matches things by size & color!
No it's NOT autism :-). I am a nurse and I work with people with various cognitive hardships. He's extremely well at talking compaired to his peers. He can enjoy time outdoors digging in sand or mud! We live on the coast & he enjoys the beach & all the different sensory experiences there. He can count, sing, dance, climb, run etc. he's just overly particular about things.
