"orphanage behaviors"

Hayden does freak out if he drops food on the floor. He ALWAYS wants to get it picked up right away if he realizes he did it. He loves water poured over his back - but SCREAMS when we wash his hair! He gets really mad when the plug is pulled on the tub. He would spend the night in the tub if we let him! He has began to brush his teeth with toothpaste the last couple days. The first week or so - he flipped out completly when we tried to brush his teeth. We backed off and stopped for a couple days and then started letting him get used to the feel by doing it himself with a wet toothbrush. Now there is no issue at all. We guess that he never had his teeth brushed in the orphanage. He also rocks his head and body back and forth and sucks his hand at bedtime (along with sobbing and crying the entire time - even with us rocking him). Helena likes to be rocked to sleep by me in the rocker or falls asleep in her swing. I'm not sure if that is orphanage or just a baby thing. She falls asleep really easily at night and nap time with no odd behaviors or rituals. One very odd behavior is that Hayden knows how to operate a shovel and a dust pan and broom properly, as well as check rugs to see if they have airdried completely outside. We are VERY suspicios that it was a "hard knock life" and that "Annie" isn't all fictional. What three year old picks up a shovel like a man and begins to dig holes in the mulch or sweeps up after himself? He certainly never saw either of us doing it - so he must either be very observant or we adopted a member of the orpahange staff!
