hi my baby is having diarrhea from last 1 week and today I gave him banana and I saw a change in poop it was yellow blackish containing something like thread and seeds it is normal

A. The threat that you are mentioning could be the seeds of the banana which are black and colour so it could be the same thing and maybe it was not digested properly which is why it came out like this just monitor the motion for another one day without giving banana and see if it gets better
