We've recently moved & since the move into a bigger house, 29 month old is really tired by about 4 o'clock. He stopped his daytime nap months ago (at home at least, he still has an hour at nursery). I wondered if anyone had successfully restarted daytime naps. Obviously 4pm is too late to go for a nap but he's such a grump by this time of day that I'm willing to try anything!
