The red, blue, and black links just have the dates on them June 1, June 2, June 3, etc.
The real fun is the WHITE links. There is one for his actual birthday June 24th, and one also one for his PARTY day June 28th.
He gets VERY VERY excited every day to take a link off. This has stopped the questioning about when his birthday is, given him something to look forward to, and we count each and everyday (a little learning) how many days until his birthday. Tomorrow there will be only 7 days! I can't believe my little baby boy will be 4!!!! He is so big!
