Approximately Speaking

As I might have mentioned in a previous post, the Early Intervention people have a term for those words a child says which aren't pronounced accurately enough to be understood by a stranger. They call them "word approximations". I'm happy to report we're hearing more word approximations in the last few days, including "help". Also, ball is sounding more like ball and Mia is trying to use her sign language more. Someone told us to write this down so we can measure progress, so here is the current inventory:
Words: Hi, hot, more (said twice a few weeks ago but never since), pop (hasn't said it for a month)
Word approximations: Dog, ball, bye, help, balloon, bottle, bear
Baby signs: Eat, more (which Mia now uses to request things other than food!), all done
Baby sign approximations: Help, ball, bear, book
