沙沙袋

My little one grabbed this during tummy time and the crinkle sound instantly stopped her fussing. It's light enough for her to wave around on her own, which makes the cause-and-effect connection click so quickly.

The crinkle texture keeps my six-month-old entertained during tummy time, and the sound isn't too loud for my ears.

My little one's eyes light up the second I hand this to her—the texture is just varied enough to keep her grabbing at it. She'll happily shake and mouth it during tummy time, and I love that it's so lightweight she can bat it around without any frustration.
