My best friend's son is staying over while she and her husband are in cancun for their honeymoon. He is 2 almost 3, the same age as my son. he's not pottytrained yet but my son is. He is incredibally difficult to take care of. He wets himself at least twice a night and then will come to my room for me to help him, he is very whiney (Something that my kids dont do thank God), he still wears diapers so I have two in diapers, he wont eat almost everything that I make, he wont go to sleep until 10 at night, he wont nap, he wakes up increibally early, hes incredabelly hyper, and he wont take a bath with either of my sons or with me in the room (Which doesnt work because I must be in there if he is in the tub) so he throws a fit until I can finally get him into the tub at which point he wont say anything to me and he constantally will hit my kids when theyre playing. Ive called his mom and she has done nothing about it. Im lost on what to do without stepping out of bounds.
