My 13 months old son has just started this week with a new childminder and when I pick him up at 6pm acts like a lunatic when we get home, really giddy and hyper active, bumping into things and being manic with massive bags under his eyes. I did mention to the childminder that when he's at home with me for the last 3 months he has had his lunch at 12pm and gone to sleep for 2-3 hours but she says he doesn't sleep at all with her, maybe 45 minutes in the buggy at 3pm when she does the school run.He does seem very happy when I pick him up and still goes to sleep without much fuss 7pm-7am so should I do or say anything? Is this nap important?Also do you the way he acts when i pick him up is purely a sign of over tiredness or are these the symptoms of her feeding him too much sugar? Really appreciate your advice, thx
