I am watching my nephew for the week for my sister. I have had him since 7am and he has done nothing but cry unless i am holding him. With 2 other children this is impossible. I know that I have been told let them cry it out but I have had him in a crib for an hour and he hasn't stopped. I fed and changed him right before I put him down. What else can I be doing as this will be a vary long week if I can't get him to stop crying?
