Has she had a hearing test done? If not get that done too, even if don’t think its necessary. Don’t correct her speech, just repeat back what she has said clearly. You are modelling good speech to her. When you are playing together comment on what she is doing, so she hears lots of clear varied language. Don’t interrupt her play with questions as this does not help her speech. Have fun and remember to turn off TV, radio when you are playing. One last thing make sure you are face to face and at her level. Cheers 1 shed.
