hi shikha - do u live near a beach or does your baby play in a sand pit? do ask ur dr if she needs to be de-wormed.

Hi shikha,, 
 @6373e6ac08ae34001598fe4b 's reply- 
Don't panic, babies;grind;their;teeth- it's called bruxism, especially when their front canines start to cut through around 8 to 12;months. Rubbing those sharp edges together helps relieve painful gums.

Dr. Praveen Singh
