my baby sitting area having pimple type what to do

A. Puss is there or not First you see that because if it is a pimple but it is not having much of a pain or no infection inside then it will dry on its own you can apply Betadine or TBACT ointment but if you see that there is kind of infection puss in it then in that case you have to clean it by puncturing it and then you can apply Betadine
