My son has orange and green patches on his tongue! What is this? It occured first when he was about a month old and was treated for thrush which took several months to clear up. Now a couple weeks later, the orange and green patches are appearing again. He is 5 months old, about 14 1/2 pounds and 27 inches long.
Hello there, thank you for posting your query with Chat Doctor, First, I would like to appreciate you for sharing the experience your baby had. Oral thrush is nothing but a fungal infection which is most common in babies and elderly, it is seen clinically as white curd like appearance in the tongue, In case of babies we advise parents to clean their babies tongue after feeding them, if we know its from poor oral hygiene. But in some cases when babies get sick their immune system goes down and that is when opportunistic infections like candidiasis appear. But according to your information here, if there is no white curd like appearance on babies tongue, nor any bleeding spots after you clean the tongue, then it may not be oral thrush(candidiasis), orange and green patches sometimes could also be stains from the foods we offer to our kids like fruit/vegetable juices. I would like you to keep an eye on these patches if they change in shape or size, also kindly take care of your babies oral hygiene. If you feel your baby is not eating well, then kindly seek consultation with a pediatrician.I hope any answer was helpful for you, feel free to write back if you have further questions. Have a nice day, thank you
