Kids grow up so fast, one day they're little and then next day they're grown... you can't get back those moments... your kids will always remember how much you were there and you won't have regrets about missing watching them grow! 

Isn't it sad that we don't realize until we're grown how short childhood actually is (and how over rated adult hood is lol). That's funny about your dad too...I keep reminding the kids about how short time is. When they say that they can't wait till this age, or that age, I tell them that they only have 365 days to be 6 or 8 or whatever age they are. Then, they will never be that again, so make the most of this age. They don't get it really, but they will.
Way to get the vegetables in for you kids!

You're a beast!

Go to bed early and see how you feel.
