The black and white contrast on these is so stark that my baby actually turns her head to follow the cards during tummy time. I've been propping the jungle ones up along the crib rail and she'll stare at them for a solid ten minutes, which is basically a miracle.

My four-month-old locks onto the high-contrast jungle animals during tummy time way longer than any of her other toys. The cards are sturdy enough that she can grab and crumple them without me worrying.

I taped a few of the black and white jungle cards along the crib rail and my 6-week-old will stare at the elephant one for a solid minute. The high contrast really does seem to grab her, way more than the colorful toys we have.
