I just started writing letters to my LO and I think I'm going to try to write one every month until she's a year old. After that, I'll try to do a yearly one.
I'm typing them right now but I think it would be nicer if I hand wrote them. However, my penmanship is terrible and I tend to like to re-organize my thoughts after I type them... not possible when you're writing on paper!
Do you write letters to your little one or keep a blog/journal for them to read when they're older?
