First of all, holy crap how is my LO a year old already?!?!

OK now that i got that off my chest, it's time to write some thank you notes. SO, from whose perspective do i write them? I feel like writing them as if they are from LO is a little cheesy, but writing them from my perspective seems, i don't know, formal? I was leaning towards writing them from my perspective but just wondering what you guys do!
