My 3yr old was late to talk relatively speaking, saying about 2 or 3 words at the age of 2.
At 3.5years he has a good vocabulary and can make 5 or 6 word sentences, often with a few wrong words or tenses (seems fairly okay I think?).
But he is still having difficulty with some letters.
He can't say z and will use y instead eg puzzle is said puyyle
L is also tricky so Lego becomes something similar to yego
And the letters n, d and t are pronounced with the front of the tongue flat to the roof of the mouth, similar to a th in this.
There are a few more but I can remember them now.
I have seen that the z and l are usually grown out of, but I wondered what is going on with the d, n and t? None of my other children did this and I am not sure if it is something that the child grows out of or needs help with.
Thanks
