If my kids were young, again, I would let them pick a wall, in their room, that they could paint or draw on, anytime & when the were ready for a change, let them paint over & start again - of course I would take a pic, so they would have it, when they got older & had kids of their own ;-) Would u do anything differently, or if u don't have kids, what do u wish ur parents would have done differently?
