my sweet boy - I know how you feel. I find it really difficult to be around other people's kids at times. It can be hard to be happy for them when I feel like we're missing out on so much stuff they take for granted.
But I can't deny that I feel blessed at other times. J inhabits the world so differently - he see the world in such a different way - that I'll always be learning from him. It's hard to put into words but it's as though his 'essence' is purer. His interests and activities will always be 'him', they won't be influenced by fads or fashions. But that's a hard thing to hold up against 'well my kid has half a dozen best friends, can ride a bike and swim 4 lengths of a pool".
