The Naughty Boy!!!!!!!

Usual busy day today, when i picked up Pete from nursery this afternoon i was told he hadn't been himself today, apparently grabbing and hitting his friends, most unusual from my little angel!!!
Anyway, his behaviour continued to concern me as he was acting like a little monster and when i got in from work tonight i was confronted by this!!!
I swear thats a devils horn formed in his hair!!!!!! Thought i'd blip it to see what everyone thought, lol. Has he been possessed today?????????
