My DS is almost 10mo, and we have just started going to playgroups. He loves going out, seeing other kids and playing with lots of new toys, but I find he becomes very unsettled (he wants to play constantly when we get home and becomes overtired) and it is impossible to get him to nap afterwards. He usually naps frequently (2-3 times / day), with each nap lasting 30mins. I'd hate to stop going, but it's quite frustrating to deal with him when he is over tired... shouldn't he be getting tired out by the playgroup and nap better??
