Now that you're 1, I have some important advice for you: don’t eat the sand in the sandbox. You can do everything else. Happy 1st birthday!
Wow, I can't believe you've already turned one. You’re so (beautiful, handsome). Happy 1st birthday!
I want to be the 1st person to wish "happy 1st birthday" to the 1st baby in the family.
One is more Onederful than you ever Onedered. Happy 1st birthday!
Wishing you a Onederfully, Onederful birthday full of Oneder.
