Two different paint colors (I like doing primary colors for young kids)
Plastic Ziploc bag
White piece of paper
These sensory bags are one of my favorite activities because there is absolutely no mess! The kids like it too because the more paint you add, the squishier the bag becomes. I like to do two primary colors to mix because you get a better result. Lincoln is 20 months in this video and he's working on color identification. The primary colors help us to repeat the same colors. I like to prompt him by saying "you have red and yellow, what does it make? Orange!" The more I say it and he sees it, the more likely he is to recognize it on his own next time.
For Layla, I'm really just trying to give her an experience she doesn't normally partake in. You can see in the video below that she's really just squishing the bag. The good thing is that she's doing something with her brother for a change. She's a sponge at this age so she's listening and watching everything he does.
*To further this activity, I also had Lincoln try to draw shapes in the paint with his finger.
