We can say this with supreme confidence: shared reading, creative play, and family bonding such as advocated by blue manatee boxes™ are always good for kids, no matter what.
However. Though developed by experts and grounded in a solid body of scientific evidence and grandparent-ly wisdom, blue manatee boxes™ can make no explicit claims as to developmental benefits to any particular child, as each develops differently and at their own pace by virtue of varied traits and circumstances. This is a good thing, as we encourage our customers to treasure every moment of this incredible process.
Any developmental concerns should be directed in person to qualified health care and/or educational professionals.
