I am having a hard time knowing what to do with a 18 month old I am watching. I have watched him since he is a newborn. I love him to pieces, but when I come home the last few months, I am exhausted from his fighting me. It is worse when he does not nap. He seems frustrated and will hit me and is having major temper tantrums several times a day. I am devoted to him and all I do is take care of him, unless he is sleeping then I read or watch TV. His parents are lovely and he has everything he needs or wants.
