Hi, I had gone through your question and understand your concerns. Adenoids are lymph nodes which are enlarged in infections of ear nose and throat,which is a protective mechanism by body. Enlarged size leads to obstruction of airway and nose cause breathing and swallowing problem. Your meta spray is a type of steroid which decreases inflammation and decreases the size. This is temporary only. Whenever you get infection it will again increase in size. Surgery is the only permanent treatment.If your baby got relieved with spray and doing fine you can ignore all the medication now. Just take care of any running nose and ear infections immediately. Concentrate on child nutrition and follow high protein diet. Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Thank you.
