Sure, babies are cute. Just ask the producers of the new documentary, “Babies,” which has become a world-wide sensation. Here in Stamford, we’re celebrating babies, too. Down on the farm. At the Stamford Museum and Nature Center, Butterscotch the goat is preparing to give birth to her new brood, and there are flocks of newborn sheep, ducklings and chicks, too. Come for Spring On the Farm on Sunday May 16 from 11am-4pm to see the babies, and enjoy border collie and oxen demonstrations, children’s games and prizes, face-painting, refreshments.
