We partnered with the KANGAROO FOUNDATION of Colombia (where the Kangaroo Mother Care Method was invented), and we are offering their Kangaroo Zak, which is the wrap that moms and dads use to kangaroo the premature babies. It is currently being used in numerous countries and thousands of families have benefited from it. We started selling them this Summer. They have been very much loved by parents and nurses alike. With the Zaky (when mom/dad are not holding the baby) and the Kangaroo Zak (to help mom/dad hold the baby), the baby will be close to the parents 24/7. The same Kangaroo Zak fits sizes Small/Medium/Large, and the other size is XL/ 2XL/ 3XL to consider not only the size of the mom but the size of the baby that will grow and the mom does not have to purchase so many sizes. All come in one color, the same as the picture of the mom with one baby.
