Regarding my niece, she does 300 words. Her major issue is she does not sit still at all and she wants to keep talking and unable to stay quiet for long. What should be done.

Ans: By 2 most children speak 3 word sentences or atleast join two words. If she is having a lot of screen time that could lead to delayed speech. I would advise you to visit an audiologist to first screen for a mild hearing disability. Once that is ruled out, speech therapy can be started.

Ans: Dear Vishal, meet your developmental paediatrician and if he/ she feels, connect with a speech therapist.
If all milestones are at age level, speak of the concern to your doctor. sometimes a child takes time to demand his/ her needs if all is being done for them without asking.

Ans: Dear Upendra,
It could be possible that she is under some sort of anxiety to get things right while explaining it.
Even a small incident from childhood where she was stopped when she was explaining and felt conscious, can trigger the same event later in life as well.
When did this stammering begin? Was it when she began talking or much later?
If much later, what event occurred just prior to that? This can be a good indicator of the WHY behind her stammering.
And why I feel this way is because you say that she is okay narrating things on her own but stammers only when she has to explain things. Also a point that you can pay attention to is: Is it when she explains anything or only certain things?
- You can try and work with this by yourself at home by allowing her to gain confidence when she explains, encouraging her rather than making her aware of it.
- Standing in front of the mirror and rehearsing/explaining can give her feedback instantly without her having to feel embarrassed in front of anyone
- Mind games to increase confidence can be introduced (you can seek the help of a therapist)
- Spend a lot of time together as a family in love and care which ensures her that she is never alone

If you still feel that things are not improving, I suggest that you visit a therapist or a psychologist who can guide her through this.

All the best!

Ans: Kindly involve her in games , physical activities more .
Use her energy into some thing more positive like activities .
You can stop giving her the screen time.

Ans: You need to get her assesment done for the current level of skill set developed.
Check out for her strengths and start simple her choice of activities to build up on her sitting tolerance. She should be able to get a vocabulary of 300-500 words at this age atleast labelling of things to be able to speak. She can point out or ask for things if she knows that receptively.
