My dd (almost 10 months) has been way more verbal than her brother was at this age. DS didn't start real discernable words (apart from mama dada and no!) until he was almost 18 mos.
DD started with a discernable, appropriate and consistent "Hiya" at about 3 mos. I swear the first time she said it was at 4 weeks, but that's just crazy talk, isn't it? Then she started with mama, and dada at about 6 mos, and has been adding words and signs on a weekly basis. Now she has Hola as well, since our babysitter and her daughter are spanish speakers.
I am constantly shocked by her noises and how
word like they sound. Tonight at dinner DS was naming G words he learned in school and DH asked him " What's the opposite of bad?" and he couldn't think of it, and dd babbled what sounded very much like Good, and then threw her hands on her head, smiled hugely and clapped and said "good" again. We all three were like

Probably over active imaginations, but she is hugely more verbal than DS ever was.
