At this current moment my sister in law, Ana, is at 4cm and still has a smile on her face...today is the day little William comes into the world. She is very aware that 4cm ain't nothing...so smile while you can, girl!
Good luck, Ana! Can't wait to be an Aunt for the very first time! (And I am sure you are pretty excited about being a first time Mom!)
Hopefully I will be given the clear to head up there (three hours away) today, but if not, then tomorrow. I am pretty certain I will take 500,000,000,000.0000000003245876523668774 pictures and will be sharing them with you all!
