Language acquisition begins before birth

This is an interesting article about sensory development, anyway, but the following definitely has educational implications:

Moms who don't mumble or slur their words together have children that can better recognize consonants at 6-to-8 months, and have bigger vocabularies at 10-to-12 months, compared to their peers. This, and other research, has led Moon to theorize that language acquisition is a process that begins before we're even born.

Think about how much catching up a five year old may have to do by kindergarten!
