Hi Prinsu. It's important that you try and talk to your baby gently about this and keep reiterating that she shouldn't do it. No aggressive behavior will work in its case and should not be resorted too as well. Remember children are gentle and only gentle ways should be adopted.

Suckling is a natural self soother for your little one when they are younger and now it is a habit. Talk to her gently. Constant mentions in a gentle conversational tone talking about why not to do this would help.
