TG,
Some of those guys above got it right. Dont sweat it, before long they are going to be teenagers and you will literally break down and cry when you see thier baby/early childhood pics. Just go with the flow and make them smile.
My youngest is almost 12 and I hardly remember what it was like to hold them as little ones. I sung them all too.
"The wheels on the bus go round and round, round and round, round and round, the wheels on the bus go round and round, all through the town....
"
Another one that drove me nuts was the one that goes....this is the song that never ends, yes it goes on and on my friends, somebody started singin it and it wont ever end, this is the song that never ends..lalalala!
Enjoy it, make them laugh and dont be afraid to be a kid again, I havent grown up yet. I think my kids like it that way too.
