My elder daughter is 4.5 years old ..n she has a habit to suck her thumb since from her birth...how can i get rid from this habit..

Hello Deep, I think you should sit and sweetly talk to her about this habit and be a party to heading towards the solution. Make her think that you both will work towards leaving this habit. And always be appreciative of her effort no matter how small it is. Say, if she doesn't suck her thumb for a few hours acknowledge it and praise her. Praise her in front of other family members and what good job she is doing to leave the bad habit. http://www.webmd.com/parenting/features/9-ways-to-wean-a-child-off-thumb-sucking Go through this link, hope it will help you.
