my son was diagnosed at birth with hydrocephalus. I believe he too has a tendency towards being obsessive compulsive. His crib cannot move to the right or left, it must be kept in the exact location it has always been or we have major problems. I think a lot of reassuring and warm gentle hugs, coupled with great patience is the only answer I have. My son has a younger brother, by 13 months, and there are times he does not like to wait, but he just has to. Good luck!! Hey you never know she may surprise you and become a great mothers helper.
