DS1 said mama and dada by his first birthday but I am pretty sure that is all he could say. Lots of jibberish babbling. I asked at his 18 month check up if I should be concerned as he still only really had a few words then and was told that as long as he seemed to listen and attempt to communicate, even if in his own language, then he was fine. It sounds like your DD is telling you things, just not in English yet.

He has really only started to gain lots of new words quickly and attempt joining them together around 2 and now at 2 1/2 he never shuts up. Especially about Thomas the Tank Engine.

Try not to worry, she will get there.
