Need help w/ wording

Hi all!
My son's 1st birthday is Saturday. I have a birthday scrapbook for him. I want all the guests to write out a little thought for him to put in his book. I have cute little papers for everyone to write on & I was going to put them in a basket or something so they can just help themselves. I need a cute/catchy saying so people will know what to do.
Any ideas?

what is your son's name?

(Name) is turning one today
We would like to remember (name's) birthday in a special way

Please write a line or two for our little birthday boy you know who!

Ok that was a little cheesy but it's all I could think of!

Actualy that was pretty good.
His name is Joseph
