Ok well I've got more....
No one told me that I'd meet hundreds of new friends on YT!
No one told me I'd run around the house yelling, "good bathroom, what a good bathroom!" or "Daddy, Harley had a good poop today" in front of company
No one told me I'd be singing the "time for a bum bath" song 2-3 times a week. (hoping that's not necessary soon though, once he's healthy)
