Baby Crying!

How many can relate to this...baby crying in the living room and teenagers arguing in another room.
Yes, I have a 16 year old, 13 year old, a 10 year old and a 1 year old. What a gap? I'm finding that it's not as uncommon as I thought. I met a man yesterday at the pool. He has a 27 year old and a 4 year old. What are we thinking?
Ok, so with me I married at 22, had 3 children within about 6 years. Divorced when I was 30, remarried a great guy and voila...another kid. :)
I plan to write more details in posts to come, but that's the condensed version.
