Hello Nidia,
Thank you for coming aboard the Disney Parks Moms Panel with your question. I hope you are having a magical day.
Celebrating a birthday at The Happiest Place on Earth is the best! Be sure to stop by City Hall on Main Street, U.S.A. in Disneyland Park or at Guest Services in Disney California Adventure Park and tell them you are celebrating your birthday for your son. The Cast Member will give him a free "It's My Birthday" button to wear; he will be sure to get birthday wishes and smiles all day.
You have quite a few choices for Character Dining. We love them all. I suggest booking a breakfast at the
Disney’s PCH Grill for Surf's Up! Breakfast with Mickey and Friends which is located in Disney’s Paradise Pier Hotel. Your birthday boy will have the opportunity to get pictures with the Disney Characters as you dine on delicious fare.
To add even more pixie dust, you can order a special cake for him to enjoy. Check out your cake options
here, and when you are ready, call (714) 781-3463 to discuss your order. Be sure that you order at least 3 days prior to the magical meal.
I hope this helps and that you have a pixie-dusted visit. If you have any more questions, please visit me here and let me know how I can help you plan your magical vacation.
Wishing you magic!
~ Lynette
