Does anyone have any idea how I can get through to ds1 (4.6) when he's gone silly with excitement or overtiredness? He just giggles manically and makes random noises, and won't make eye contact - if I hold his hands and try to keep him in front of me to talk he goes all floppy and giggles on the floor instead... It doesn't take all that much to get him excited - especially since he started school in January.
