How do you clean lo tongue? It is so difficult to clean the inner part of tongue..currently using washcloth to clean but she doesn't open her mouth big enough. Any advice?

how old is ur LO? tell baby "ah" n then insert ur finger and clean. maybe use a smaller finger like Little finger if need to? clean whatever u can. the point is to somewhat clean and get them to expect mouth cleaning early which will change to teeth brushing soon
