I kinda like to say that I home school my children or maybe it's better to say "unschooled" since I don't follow any book or anything... But I try to keep them busy, but busy in a way that I let them learn on there own. I show them stuff, yes, but I really let them discover what they can do by themselves. I must say that there very good at making necklaces! :)
Oh, and also. It's important too have a calm environment, it can be stressful doing activities with kids, so I would suggest : take a deep breath, put some music, don't make a big deal of the mess and be very patient.
Happy mama=happy kids :)
Have a great rainy day !
