Helpppo, 2 year old has been pooping like this for 2 days going on 3rd day. TMI PIC

It’s more like yellow idk why it look brown.

It smells disgusting

She’ll been running her clothes for 3 days now she poops and it runs down her legs

It’s really really foul smelling

Does she have an infection? Upset stomach? Idk she’s getting really weak too.
