I think you need a schedule. I am seriously considering following the schedule my center uses- free play, then circle time, walk outside/ playground, art project, lunch, nap, snack, free play (eg dolls, dress up), another walk or other outdoor time (water table maybe?), craft project of some sort, reading books, music time. Then another walk to make it like they are being picked up from daycare, home for dinner, bath, bedtime.
