What are some fun babysitting activities I can do with a 4 &7 year old?
First off, make sure that the parameters of crafting are known, such as where they are done (if that makes sense). Take them outside and let them paint but make sure that they don't ruin clothes. If the 4 year old knows their numbers, you can play Go Fish and similar games. If you know any card tricks, ask them if they want to see a cool trick and if it's easy enough, teach them too. Playing School is fun, especially if they're the teacher. If you know any origami, make some origami.
flashlight tag you turn off all the lights and get a flashlight for each kid and and one can be it and the other can hide when they find the ither kid they have to try and get to base without the light touching them you can also play a fashon game and let them dress up in their parents clothes (if its ok with their parents)or your clothes
The Sleeping Game!!!
