DOES SHE HAVE LANGUAGE COMPREHENSION?

I had 2 nurses to look after Sushmitha. Now both are leaving the job permanently. My brother in laws son got married. Sushmitha would have enjoyed the family function. She likes being in stage.How she liked the dancing onschoolday. I sometimes feel she can understand somethings. Like when Anitha told to look at your mom she she shifted her gaze towards me.We were in hospital on 6th. So when i asked we will go home she said ha. when coming back from ambulance I asked her should I hold you tightly she nodded her up and down as if she wants to say yes. Today mom told her i want u and nobody else she again told ha.
