My kids are getting older now (4 1/2 and 6 1/2) and they are really growing up! I've been getting a bit nostalgic lately about all the things I'll never do with them again:

* I don't think I'll ever rock them to sleep in my arms again. They are just too big!
* I won't ever push them in a stroller again. We don't even own a stroller anymore! But my son used to struggle to sleep at night, and I would spend hours pushing him around the block in the middle of the night.
* I noticed recently that when my kids got cuts lately, they asked for a bandaid - and not for a kiss for their booboo. I never liked kissing their booboos (so unsanitary!) but now I kinda miss it.

Of course there are lots of things I don't miss (changing diapers, waking up in the middle of the night, etc.) - but I never expected to miss so many little things that I never really thought I would value!
