We can say this with supreme confidence: shared reading, creative play, and family bonding 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™ make no explicit claims as to developmental benefits to any particular child, as each develops 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 to qualified health care and/or educational professionals.
