DS is 2.5 and flips between hyper and lazy, pretty normal for a toddler I believe. He can be really hyper and hard to calm down at times and we're used to that.
However, tonight after his dinner he was simply going nuts. He was running in circles to make himself dizzy, jumping on the beds (something he never does), running, screaming, kicking the walls and generally behaving badly. He was scarlet, presumably from the energy he was putting out and we were actually getting quite concerned at some points. He was like this nearly an hour until he then decided to refuse to let us in his room (sitting behind the door) and cried. He then went to bed without a fight at all. DH made a joke "what the hell did you give him for dinner" and it's actually got me thinking. He had loads of carbs and also tinned sweetcorn (the sugar/salt water stuff) that he never usually eats.
Could it be that he had extremely high blood sugar? Should I be concerned at all? DH is away tomorrow for 2 wks so it's quite possible that all of this was a performance for him...
