Here's how I know....

That I made the right decision to stay at home with Isabel. Because even when I am changing her diaper in the Hob.by Lob.by bathroom, and she is screaming bloody murder, enough that people come to check on her and then she later poops through her diaper and onto her clothes in the middle of Koh.ls....I still know without a shadow of a doubt that there isn't a place in this world that I'd rather be....except for maybe at home. :)
