It’s hard enough for your Indo-European proto-speaker to figure out thousands of years of language change from Proto-Indo-European. It’s even harder when those changes are less regular than your baby. Mamas, don’t let your neo-grammarians grow up to be Neogrammarians. Get them the S-Mobile, the toy that lets your tots discover the messiness of diachronic linguistics through cute animals! It’s the only mobile guaranteed to improve your baby’s reflexes!
The S-Mobile is another fine educational product from B-Cos®, the first word in language learning.
