My daughter and I did a few different activities this year for Valentine's Day, these were our favorites. <3
Hearts and Bubbles
I froze bubble bath, food coloring, and water in popsicle molds, and let her mix them into cold water to make bubbles! She squeezed heart shaped sponges with her hands and a citrus squeezer.
Color Reveal Hearts
I drew hearts with washable marker in different colors, drew over them in black permanent marker and wrote the color underneath in Hindi. My daughter and I are both learning Hindi :). When my daughter dropped water over the black hearts with a dropper the color underneath was revealed and she could more easily read the Hindi with a color reference.
