my mil did this years ago in england, when she had dh and his brother, she was new enough to the area, and met some girls through work and then through mother and toddler, they became friends and would then do babysitting swaps, they would build up credit with one another, say a credit and hour and then exchange it with one another, she said it was great as times were tough and also NO INTERNET way back then….
obviously she had no family to babysit so they did this and was a great thing to do….
so get babysitting swapping….why not….
