My ds is 26 months and had always been a tad tetchy when he wakes up after his afternoon nap. But over the last few weeks, its gotten quite crazy. About five minutes after waking up (its the same whether I wake him or let him wake up by himself) he starts crying and screaming and nothing I do seems to make it any better. Most days I manage to get him to drink or eat something and he tends to cheer up after 15 minutes or so and is then his normal, lively and happy self. I'm wondering if it might be his blood sugar levels (he's never affected like this in the morning when he wakes) that cause this kind of mood change. Does anyone have similar experience/advice? Thanks, Lorien
