Babies and toddlers use all 7 senses to learn, and sensory bins are the perfect way to engage your little one in play. They’re ideal for fine and gross motor development, stimulate multiple senses, help make connections, and keep them busy for longer than most toys would. Search “sensory bin ideas” on Google or Pinterest you will get tons of inspiration and ideas, for all ages (kids continue to enjoy sensory play for their entire childhood). Here are some of my favorite sensory supplies — don’t forget to buy an actual bin (an under-the-bed storage box is great for this, as is an inflatable pool for easy cleanup and to keep everything contained.
NOTE: if your child is still in the put-everything-in-their-mouth phase, anything you put in the sensory bin should be taste-safe, non-toxic, and you should avoid choking hazards. Use fillers like (rice, water, snow, chia seeds, cooked spaghetti, cornmeal, jello, cherrios, nontoxic playdough, homemade sand). Once they get out of that phase, you can start to expand their sensory to more items (dirt, slime, kinetic sand, uncooked pasta, beans, pom pom balls, shaving cream, water beads, etc.).
