it DOES get easier as they get older (you need to babysit a 2 year old for 10 minutes if you've forgotten.)
You can leave them long enough to go to the store, at a certain age, and then at another certain age, you can leave them for an evening.
I'm not saying that I am not still tied up in knots (sorry Knot) about stuff involving my two sons (with DH saying, let it go, they are 26 and 28 years old)
but guess what? I can leave the house for the week and when I come back everythin'g is just fine!

so yes.. it DOES get easier.
