How should i clean my 9 months baby's tongue??

you can use a damp cloth to gently rub your baby's tongue. make sure you do it very gently as else baby will get uncomfortable and next time may not let you do it. there will most likely be a thin white coating on the tongue at this age, so try and clean the tongue at least twice in a day. also, if you are starting your baby on brushing, clean the tongue even then
