Here are some fun indoor activities that you can spend "Quality" time with your kid/kids :
Blowing Bubbles
Making your own bubbles couldn't be easier! You can use liquid hand soap and a bit of water to do this. All you would need is a bubble wand, which you could create out of a bit of thin wire(left over Easter Egg wire dippers would be excellent for this), and a container for the bubbles(you could simply use a bowl or plastic container for that) and you're all set.
For smaller children, try picking up some "tear free" shampoo to create your bubble mixture with. Do remember that the more "foamy" a liquid soap is, the lower quality your bubble mixture will be. Now, to create your own bubbles, simply take 1/15 cup of liquid soap(actually it is said that dish washing liquid works best) mixed with 1 cup of water inside whatever container you want to store it in.
Bubble mixtures of liquid soap and water can also be mixed with glycerin, sugar, or corn syrup as well. For even more bubble recipes, check out this websites : Homemade Bubbles
Giant Easel
Go to a charity shop or wallpaper shop and buy leftover rolls of wallpaper. Cover a wall with the paper, back to front, stick it up with blu-tac or drawing pins.
Give the kids paints, crayons, chalks pens etc and let them create their own frieze. The little ones reach the bottom, whilst the big ones can reach up to the top.
Board Games
Almost every family home has one form of board game or another. Whether it be your standard board game such as Monopoly, Sorry, Trouble, etc., or a DVD type trivia game, these can provide hours of fun.
While DVD style games are fun, the classic board games are better as you will never have the same outcome. Meaning, even though you are playing the exact same game, the winner is unknown until you have finished the game.
Try spicing up the game by playing for different types of prizes, but be sure that everyone will win something. The prizes could be dividing up chores that are to be done, having the 1st place winner getting the easiest household chore and the last place winner receiving the more difficult, or the chore that is least preferred by all family members.
You could also try having the prizes consist of allowing the 1st place winner pick tomorrow's activity, 2nd place winner picking the following day's activity, and so on.
If you don't have a board game lying around, why not invent your own games? Activities such as "treasure hunts" can be fun and educational at the same time. You can create your own maps or clue lists and let the first place winner(s) have first pick at the treasures. And, of course, the treasures can be anything you can think of that would have significant value within your particular family unit.
Also, a good game of hide and seek can also be hours of fun for all ages. And, hide and seek can be played both indoors or outdoors depending on the weather.
Turn each day into a memorable adventure of fun for everyone! And remember, money doesn't make memories, YOU do! :-)
