C.O.
C.:
Sorry - I would wait and let my husband go first. Changing schools mid-year is hard for ANY child. It's 4 more months. Although I don't know your situation, if he's been commuting for however long and you've decided to move - why not wait until the end of the school year and do it then?
If this move will save your family a substantial sum of money (assuming you own the home you live in right now and can sell it fast), I would figure a way to make it work for the last 4 months of the school year. Put the home on the market and see what happens....
ETA: As a military brat/dependent - I understand the moves. We were fortunate to have summer moves instead of mid-year moves.
GOOD LUCK!
