Debating over his age

While on the way back from the breakfast, Jayden was telling me that he enjoys watching Mickey Mouse, Goofy and Donald Duck.. Then, I told him that he can meet all of them in Disneyland.. So, we had a little conversation on the way home.. 

Mommy: Hmm.. If everything goes smoothly, maybe we can bring you to Disneyland when you are 5!

Jayden: What is Disney mom?

Mommy: Disneyland is a place with Mickey Mouse, Minnie Mouse, Goofy, Donald Duck, Clarabelle Cow, and many more. 

Jayden: I wanna go Disneyland to see Mickey Mouse, Goofy.........Cow

Mommy: Sure.. Let's plan. You are now 3...

Jayden: No! I am 4! I am not 3! Ms Callie said I am 3, I don't like it.. (Ms Callie is his teacher at school). 

Mommy: Well, you are still 3 because your birthday is not here yet.. You are turning 4 really soon, in about 2 months time! When you celebrate your birthday, I will buy you a cake with 4 candles, then you are 4, OK?

Jayden: But mom, I am 4.
