Hey, I have 14 month old twins. They both have recently been treated for ear infections and just finished Monday Amoixicillin for the infection. On Tuesday they both got RSV vacs. That is when I first noticed one of them having a think white coating on the back of his tongue. It covers the back 3/4. It is not on his cheeks and does not seem to be sore.
Thanks for your query, I have gone through your query. The white coating on the tongue could be because of the food debris(coated tongue) or it can be secondary to the antibiotics. Nothing to be panic, maintain a proper tongue cleaning soon after feeding. If there is any increase in the coating, then consult a pediatric dental surgeon. I hope my answer will help you, take care.
