After months and months of struggle I finally got my 10 month old lo into a lovely sleep routine where he would calmly (well, sometimes calmly, sometimes with a bit of protest) go to sleep at about 9am then again after lunch. Only for about 40 mins max, but it was bliss and kept him chirpy most of the time. Now he has worked out just how much fun standing up is and it's all he wants to do. Nights aren't too bad, but in the daytime he gets really tired and grumpy, though later than he used to, and refuses to sleep because there is standing up to do. I try putting him in his cot for a bit of time out to see if he'll sleep but if he does it usually takes a long time and a lot of stroppiness. Anyone got any tips on getting him to nap? Or should I just forget about naps altogether and keep him up? If so, how do I keep him happy?
