When I was a little kid things were no where nearly as elaborate as what people do today. Taking the kids to the roller rink or ice rink was popular in the winter months. In the summer, it was minature golf and backyard parties with games and pin the tail on the donkey or a pinata!

Have an indoor scavenger hunt..maybe have them wear costumes and come up with a theme..princess..cartoons, Disney, etc. Little girls love Tea Parties too!

Have a "Frozen" party!

You could let them decorate their own cupcake or large cookie and have a large variety of decorations from M&M's to sprinkles, to chocolate chips , to small candies like Ike and Mikes or gummy bears etc. Children love activities so plan on some games to play in a basement or area they can play without hurting anything or themselves to a modern version of pin the tail on the donkey changed to pin the carrot nose on the snowman in Frozen or some such modern movie they love. A photo of most characters can be printed off the computer and paper carrots made easily enough, use tape if you like rather than pins. Then a contained scavenger hunt would be fun, get them to use their imaginations like don't tell the objects list them with a description: i.e. something stretchy (they find a rubber band) or something fuzzy (they find a fuzzy toy in the toy box) etc. You could read the list one by one as they bring in their object. Also, we had our invited friends come dressed to the party as a favorite GOOD character (no evil ones) and gave small prizes for everyone coming in a home made costume (we stipulated no store bought ones) or have them dressed as a character for a theme, like if you used Frozen as the them they come as one of the characters. Or for no stipulations on costumes: Simple antlers left over from Christmas and a brown cape , and a black nose could suffice for the caribou, or carrot nose and white stuffedsheet with belt for the snowman etc. Or take from a gingerbread house theme to make a castle for all to decorate like in frozen movie, there are many things you can do. What is your child's favorite movie or animated character? Play on that for your theme and plan activities for it. They could even build their own mini pizza and an adult heat them after they put everything on they want. etc.

My kids always had fun with a balloon stomp. Blow up some small balloons and tie one to each kid's ankle with a piece of curly ribbon, so it hangs away from their ankles (1-2 feet), then let the kids stomp on each other's balloons. The last one with an unpopped balloon wins a prize.

My granddaughter's sixth birthday party was a painting party, like the wine and paint parties for adults, minus the wine. My daughter sketched simple snowmen on flat panel canvases, providing small paint pallets with paint from large paint containers she purchased in basic colors. A small container of water to rinse their brushes in, clearly asking the children to wear outfits they could paint in on the invitation (and some plastic aprons) was the main setup. My daughter bought inexpensive supplies in bulk, and one large canvas for them all to paint. The small canvases went home with them (and many of the adults who stayed did paintings also) and the large canvas hangs on the wall of my granddaughter's playroom as a memory of the fun they had.

If you live in an area with snow, a sledding party is fun. Many ski hills also have tubing facilities and offer party packages. A fun indoor activity is to provide Styrofoam balls and different decorations for the kids to make their own snowman to take home as a party favor.

Lots of places have indoor swimming pools or indoor water parks...have a luau as a nice break from the cold weather.

Ice cream parlour, zoo, tea party.
