Speech delay

RJ

Hello ladies. My daughter is 28 months. She has speech delay. We have put her in speech therapy. She is getting sick back to back in a month. So from that time her focusing have become poor. Like she used to nicely listen and focus on what i told her. These days she is not focusing at all. Feels her she is being in her own world. Not getting what we say to her. Iam so worried.

What to do? Any suggestions pls
