A few doctors told me that too for my daughter - I didnt go to any therapist at all because my mother (daughter's grandma) said - just play with her for a few extra hours a day and you will understand what she says, she was speaking alright - but in her own language. We just corrected her later on and made words from her babbles. She rotates around urdu/english - and children under 5 can process as many languages you can throw at them.
another thing that helps is that you give your child proper food to eat - the food should be something that requires chewing. (was told to me by my aunt aka phupi)
now - I have another problem, she wont let go of me as she finds that I can communicate with her properly.
