3. DIY Sensory Bottles

Sensory bottles are simple yet captivating for one-year-olds. Grab a clear plastic bottle, fill it with water, glitter, beads, or small toys from Dollar Tree, and seal it tightly.

Your child can shake, roll, and watch the items move, which encourages visual tracking and fine motor exploration. You can even create themed bottles—like ocean or space—by adding small themed objects.
