Jump for joy! – it’s time to invite your child’s friends to celebrate the milestone of another year with our delightful number or age theme birthday party invitations! Your search for unique birthday boy and girl party themes has ended – who could resist a little boy or girl jumping high, arms raised, shouting, “I’m Two!, I’m Three!, I’m Four!….” No matter what age your child is celebrating, that age is very important and the world needs to know. Choose from 9 boys and girls with different skin and hair colors. Choice of font colors also available for number or age theme birthday party invitations.

Your number kids will love taking home their personalized favor bags matching the number or age birthday party theme. Fill the bags with candies and nuts. Your number girl or boy will feel extra special wearing his or her very own personalized number or age theme birthday t shirt, announcing the milestone of their new age as they kick up some fun. Or perhaps they’d prefer our personalized kid birthday t shirt with cake, candles and child’s name and age. Looking for number or age related gifts? Check out our number kids personalized magnets to hang on the fridge. Kids also love to have their own personalized birthday cake Christmas ornament showing the number of candles on the cake and the year.

Jumping on a trampoline, swinging at the playground, playing a game of tag at the park, a day of backyard fun at home - wherever the party was held you can be sure those number kids are hungry and ready for cake and ice cream. Finally Mom or Dad can send those tired number kids away with their own matching number or age theme party favor bags. Clean up the mess, pack up the new gifts, and then it’s time to say thanks! If your young number kid is too tired to write a proper note, the problem is solved with our fill-in-the-blank thank you note cards, perfect for number or age party themes! More verbal kids might prefer our folding number or age themed thank you note cards that are blank on the inside.
