No it won't cause any problem. My cousin brother had same problem and it went of it's own. Nothing to worry about but if this problem persist long then tie a bandage on your baby's finger during sleeping time your baby will not take it in mouth. It worked for my brother. Hope my answer will help you

Hi get a stool test done for ruling out any infection
