The folded-hands emoji means 'please', 'thank you' or 'praying for you' depending on context. It is one of the most commonly used emojis worldwide. Some users — especially in some Asian cultures — read it as a bow (greeting/thanks); others read it as praying hands. Both meanings are accepted. Among Western teens it most often means 'please' (when asking for something) or 'thank you' (when receiving help). There is no negative or coded meaning. If your child sends it in a request message, they are politely asking. In sympathetic messages, they are offering support.
