A very easy activity for kids is letting them play with shaving foam. It’s easy to clean up with water and is lots of fun. It’s not good to eat though, so I prefer not to let Baby T near it, but L and A love squishing their hands into it.
We used a couple of plastic trays on top of a muck mat, in an attempt to contain the shaving foam. It’s nice to do this outside if the weather permits, where we can just hose the area down. L and A each had a tray with shaving cream in it. They used various utensils to mix and scoop it, but mostly they just liked to feel it, squish it and squeeze in through their fingers.
L pretended the shaving cream was part of her cafe and she made me a smoothie. A whipped her shaving cream up with a whisk, and somehow managed to get shaving cream all the way up her arms and on her face.
We have previously used shaving cream to practice writing spelling words in too. We just smooth a layer of shaving cream in the bottom of a tray, and then write the words using a finger to form the letters.
