Ok I am going to try to think of all the words she can say...
She can say hello, hiya, bye bye, daddy, mummy, baby, DD1s name, doggy, eyes, ears, nose, mouth, toes, head, bum and can point to them all. Nappy, door, book, juice, cup, chips, chicken, tshirt, spoon, num num, nice, thank you, go, down, up, night night.
She says things like "its ok" "there you go" "here you go" "come here" and may or may not add a name to the end of these if shes directing it to someone.
She has names for cbeebies characters that wouldn't make sense to anyone else but that we understand.
She can respond to me asking her to get something or do something (when she wants to lol) and she can point out things in books. She can make a few of the animal noises but usually just waits until we do them and then laughs at us.
Her pronunciation isn't entirely perfect with all this, like cup is bup and spoon is boon, but most people can understand what shes saying.
That's nowhere near 150 and there is absolutely no way we would have anything that resembles a conversation. I would ask her a question and she says mm hmm no matter what I ask.
