Hi, it seems impossible to me! Its been 2 nights in the big boy bed and he's not doing too badly - am v. strict saying I will shut the door if he keeps coming out. But daytime,I can't seem to get him to sleep. And he gets more and more hyper and hard to control as the day goes on. He could listen to story cds but he just won't stay lying down. Any idea's, or shall I just give up? He wakes at night too but that's another story. Is it possible he will just adjust to no daytime sleep and sleep longer at night? Thanks for replies!
