I also have my own 3.5 yr old and am literally counting the days till he goes to full day jk. (I think it's 161 days) some days he's great but about 3 of 5 days he's a terror. Today was one of them, so I sent him upstairs and he had to play in his room. All my kids have their special toys in their rooms and the toys in the daycare are my toys. That helps a lot. I also bribe him with an opportunity to earn 30 mins of tv before his nap. But if he doesn't behave no tv. I never use the tv during daycare hours so that is special to him.
