YABU- I wouldn't
YANBU- in a heartbeat
I would. I miss running to the otherwise of the playground because walking was too slow. or walking along walls because the floor was too boring. Stuff like that. I read quite a lot of books written from a child's perspective. And listen to the hits from when I was about 5-8 whereas my DH listens to music from his teens and early twenties. My parents have said they would go back to being a young adult over a child.
I am in the midst of child rearing but when this is over I suppose I would long for these years and might forget about my own childhood.
