18m old and diarrhea

Hi moms, what could i give my little one?

He started with some diarrhea yesterday, runny and super stinky! (Had about 4 runny diapers all day)

This is the first time he’s ever had it, he has been drinking LOTS of water so thats good but he’s not eating much.

Im going to head out and get some pedialyte as well as yogurt with probiotics? I was reading about the BRAT diet which i gave him some toast and a banana this morning. He ate everything so far so thats good, we’ll see how lunch goes.

Anything else i could give him that helps?

Food wise, med wise?

TIA

One more thing, hes been drinking water like crazy YET his urine is still pretty dark 🤔👇🏽
