Our kids moved into the neighborhood with four of our grandkids. They have been homeschooling, and are continuing while riding the fence about putting their kids into the very small public school here in the netherwoods. I am encouraging the homeschooling option without being judgmental if the decision goes the other way.
I have invested significantly in used musical instruments, and am giving music lessons to mom, dad, and the two older kids (11, 13) though I am woefully underqualified. Mrs Sailor and my mom (now GG) are both jumping in with keyboard lessons for the young girls (4, 11). This is turning out as well as I could have hoped for with their family practicing music together... and the older generation being involved too.
The two younger ones (6, 4) are not in a mood to be left behind and are demanding turns on Mom's euphonium and big brother's trumpet. I am adding a couple more student horns to make sure Mom gets fair time on her new venture... and the little ones can grow at their own pace.
Used instruments are surprisingly affordable ($75-$150). Ones with better long-term playing potential cost more , but I found some deals because they needed service ($250-$800), and happily I was able to blunder my way through the service to nice playing instruments.
It excites me that the young family is playing together; growing together musically. It excites Mom and Dad that their 13-year-old has a musical outlet as he seems to be developing a bit of the surly when he doesn't play music. He is stretching out and "doubling" on the trumpet which he has had a little public school experience and the trombone which is new to him, but great new fun.
Music operates in a segment of the mind that little else works. It makes a big difference in overall development and should be part of your homeschooling if you can figure a way to pull it off.
