Yeah Kids pretty much want to do what they want. DONT stress yourself ot alot about it. Its so much easier when the bdays are in the warmer weather!
Id ask HIM, his opinion. Since its His day he will love to put some thought and input in im sure. I agree 100% with the movies and popcorn and snacks, Oh and Pizza!!
Have some lil food trays set up to munch on. I did chips, pretzles, dip and then a veggie tray & dip. That way its not all unhealthy food.
Also a cool idea is make your own pizzas and sundaes! or maybe a slushie maker thing or make them in your blander if you have one. I seen some realy nice ones at target and have one from Walmart. They are nice! and you can make koolaid or pop slushies if you dont have the sno cone syrup. I know I have a slushie recipe around here too! And im sure you can find some online as well!
Rent some video games and have some board games handy to play. We have tuns of board games and we usually let the kids pick out one for bdays and such..overnighters!!
Theres alot of things yu an do with the kids.
Just ask your son some things he might enjoy doing?
Coloring books/crayons/markers
Painting
make a ALL ABOUT "your son" Trivia and see who knows him best?
treasure hunts are way cool! and kids love them at any age!
maybe make up sopme specail things/packages for the boys staying over.
You can even do like t-shirts with them or pillowcases or anything! Take pics!!!
