Babies are too smart. They are interested in fidgeting with objects their parents and siblings use daily. This board might amuse them temporarily, then it's on to the toilet, the beer cans, stove, mic stand, laptop, trash can, dog ears. The world is their oyster and fidget board is just false signal because daddy always touches his mobile device, dangerous tools and beer cans.
Cool thing is that whatever you do for them, is worth it.
