White or red tongue coating and bad breath in toddlers may be caused by a preference for sweets, coupled with failure to maintain proper oral hygiene after consuming sugary foods, leading to long-term bacterial growth. It could also result from weakness in the toddler's spleen and stomach. Additionally, if good oral cleaning habits are not established and the child does not rinse or brush their teeth promptly after meals, these symptoms may also occur.
