How many words at 2?

[Early Kids]

Brendan had 2 words("dadadada" and "da-da" (like ta-ta)) and the car noise "brrm" at 25 months. He could also babble "mumumum" "nanananan" and "bubububub" but they were just sounds, he didnt connect them to the people until closer to 30 months. He could also wave, clap and point. And point to his ears, nose and hair/head.
Brendan is now almost 32 months old and only just a few days ago put two "words" together... "ta mum"

At Brendan's 2yrs corrected check-up (27 months actual) they wanted Brendan to have approx 200 words, that he knew the meaning to and understood what it was he was saying. On top of those 200 real words they wanted him to be immitating words and to be able to follow simple commands, none of which he could do.

We've been attending Speech Therapy since he was 11 months, it started off eating related and moved onto speech. At almost 32 months Brendan has 21 words, including some animal noises, has two sentences 'bye-bye' and 'ta mum'. He tries and mimics several words, approx 10. He can follow approx 10 simple commands, 'put it in the bin' ect.

The biggest thing is not the speech itself, but the understanding. As long as your child can understand a lot of things the speech will come on its own eventually.
