Always a fan of chalk on the patio or cup of water for ‘painting’ the patio when I’m tired also a bowl of water and bubbles to wash the garden stuff whether it is a wendy house slide or plant pots.
Dolls also needs a bath, washing their clothes too and then a mini washing line
A bath will kill quite alot of time, do you have bath crayons or some toys/stuff from around the house that doesn’t normally go in the bath?
Playdough, adding essential oils especially lavender is gorgeous when played with.
Good luck x
And if all else fails some tv, a dvd with popcorn and dimmed lights, bung loads of cushions on the floor and put your feet up. Or a game on the laptop, angry birds is popular here
