my baby 13.5 month old she poops 6 to 70 times daily with a little mucus with normal consistency why

A. I believe it’s seven times, not 70 times as it is getting flashed in your question. Sometimes children have a normal habit of passing multiple stools per day, but with mucus is definitely not normal. I would advise you to get a stool routine microscopy done . Any infection in the report can be treated accordingly
