Vivi (she who has so far preferred shrieking to speaking) this weekend added six words to her vocabulary - about one every three and a half wakeful hours:
flowers (which she used a few times months ago)
boot
Daddy (versus the former Dadda)
bowl
Bert (as in Bert and Ernie; she prefers the yellow one)
and, critically, bye-bye (she was ridiculously insulted when we noticed she'd nonchalantly said this as she walked away from a toy)
