NSFW (infant poo pic) - what are these lines in my 7 month olds poo?

Sorry just noticed them lately, he’s crap at weaning so not taking much solids in just yoghurt really… what are these darker lines? Almost like e string consistency

Can’t see a pic but I seem to remember banana poo can be very wormy looking!

Why are you regarding this as " not safe for work"?

I just didn’t think someone would want this popping up on their work computer in an office 😂 good shout! He did have some banana the other day!!!

I definitely remember being quite concerned about the banana weaning poos!
