Manners must be taught. And not only must they be taught, but they must be enforced and reinforced all the time. Seriously, multiple times at every meal. While it may feel redundant (and a tad annoying as a parent), it is too important to let slide. Manners do, and always will, matter.
This is why our new set of Hello Genius board books focuses on manners. Reading these books will help reinforce manners in a sweet and funny way. Believe me, I read them almost every night.
