I'm curious to hear how your LO's language developed, specifically:
How many words at one?
How much receptive language did they have at one?
If LO was older than one when they really started saying words and showing they had receptive language, how old were they?
If you were worried about delays, at what point did you/would you seek an early intervention consult?

I think the boys are a little slow in language development, but I'm not really concerned yet. I'd like to know how various kids' language developed and have a better idea what's within the "normal" range and what to watch for.
Both my boys are physically at or ahead of where they should be, I think. They started walking at 10 1/2 months (9 1/2 adjusted). They pick up food, bang toys together, babble lots of sounds. They wave at people and point at things, but not in relation to us saying something like, "Where's the dog, cup, etc."

E says "go" pretty consistently when we take the dog outside and tell her to go to the bathroom. He's also said mama and dada but not often and not in a way that makes me positive he knows that means us.

F says "bye bye" occasionally and has said dada in a way he definitely meant DH. He chatters "mamamamamama" but hasn't used it to mean me.

I'm okay with them only having a couple of words, but I'm wandering more about how much receptive language they should have. They don't seem to really know what any of the common words we use mean. The only words that they've shown a clear response to is "no" and their names.

So, tell me about your LO's language development!
