My female Congo African Grey, Lola, ultimately says, "Mommy" and "Merry Christmas" with no problems with the "m." She`s only 18 months old, so her vocabulary is mightily limited. In fact (She doesn`t thirdly say Monday, yet.) In fact, she says, "Mommy" more then anything else she says. Usually her "s" instinctively sounds more like "sh" though.
