Hello my friend I am Dr. Arianisa Thanks for your question on HCM I understand that as a parent you are very concerned but worms can be treated. There are many types of worms and they are usually divided into three groups: 1.Roundworms - the most common roundworm infections are thought to be caused by threadworms, ascaris, hookworms, and trichuris. Roundworm eggs usually enter the body by the person eating food or drinking water that contains eggs 2.Tapeworms 3.Flukeworms The most common worm infection is threadworms - this is a type of roundworm and is sometimes referred to as a pinworm. Threadworms are spread by being in contact with someone who is already infected with threadworms.Threadworms look like thin, white, cotton threads.I think this is the type of worm which have your baby Piperazine in the form of an elixir or mixed with senna as a powder may be used in children under two years. It would be wise to see your GP so that the recommended dose can be prescribed. I hope the treatment is successful Hope this information is helpful to you Best regards
