I defintely get what you mean for the babymach part. I think that's a cute idea and I do get that fun kind of carefree feeling with the things you've named the pages and all. I like it!
And I know th'ts just how you type. :) I really don't have a problem with it, since I know you and all and it's fine for like, personal communications.. I'd just hate for someone who doesn't know you to make a judgement on something silly like not capitalizing the beginning of sentences, ya know? (Just because I'm a bad person and know that I would if it wasn't a momma I knew.)
