Hi,

Thanks for writing to XXXXXXX

You can try applying femite oinment on his thumb twice daily until the habit goes away.

More important : divert his attention to some hand based activities like building blocks , etc .
Kids suck thumb when they feel insecure. Make sure someone is there all the time.
Ensure frequent feedings to avoid him getting too hungry.
Do not use electronics like tv/ etc.
Engage him in some kind of physical activity
And do not punish him for sucking. Rather reward him for not sucking.
Kids need positive reinforcements more .
You cant get rid of this habit suddenly. Go slow, hope your kid will stop sucking soon.

Hope this would solve the issue. Please let me know if I can help you further.

Regards
Dr Arun
