My child is a genius (At the very least amazing)

So tonight after I got off of work, Michael wanted me to "play tracks and trains". He always lines them up in the same order so when the last 3 were missing, he knew it. He turned to me and held up 3 fingers and said "3 trains missing - yellow, black, black" Then we searched around for a minute and found the yellow one. Then he held up 2 fingers and said "2 trains missing - black, black". The things this kid knows amazes me!!
