I have a little kitty, probably 2 to 3 months old.. he keeps trying to nurse on my jammies at night... he doesn't do it any time other than at night.. I wonder if he needs milk, altho, I have heard that milk is not good for kitties after a certain age... or if this is just a comfort thing??

At her age she doesn't need milk. Also cats are not supposed to have cows milk. I have 4 and they never get it and seem to do just fine.
It is a comfort thing, it may have been weaned to early. Cats normally have their kittens by eight weeks though. Hopefully as your kitten grows older it will become less inclined to do this. If you find this annoying try to get her a blankie made out of the same material that you jammies are made from, when she starts suckling on it then slip that one under her, it may take a few times but hopefully she willl seek that out when she feels the need for comfort.
