Because it's hard not to get involved when the children are playing with paints.
Muuuum, I need some more paper.
Mummm, my water's gone all black, can you change it?
Mummmm, Sam's put his hands in the paint and he's making a mess.
Mummmmm, it's not fair, Maddie's got the thin paintbrush and she's had it for ages.
Backwards and forwards, fill water pots, replenish paper stocks, refresh paint palettes, supervise Sam with painted hands, referee over paint brushes.....
Stop to admire artwork.
Somehow in the midst of it, try to put something together for dinner.
