My 18mo DD only says three words: No (which she uses to mean yes and no), Dad (which she uses to mean Dad and Mum) and milk. She understands us when we speak and makes noises and gestures to communicate, but she is going to nursery soon and I would like her to have more words to use there to make friends with others her own age. What can I do to encourage her to learn more words? Are there any books or flashcards you can recommend? Or should I just stop worrying about it and let it come in its own time? I was a late talker myself (didn't say a word until 22 months). I'm perfectly capable at communicating now, but I had a bad lisp at primary school which I'd like to help DD avoid if possible. Many thanks in advance for any suggestions.
