Servus love her.. I’m confused.. if my baby is standing a day or longer.. lights up the oil lamp for a long time.. although he doesn’t lose oil, or there’s too little oil in it.. then the moth also runs a little louder that’s such a “knocking” . .. after one to two minutes – sometimes more.. the oil lamp goes out again, and it goes on normally.. can anyone possibly tell me what that is??? and/or how I get the problem cleared out of the way??? Thank you and love gruesses
