Diarrhea for about 24 hours

Ta

My little guy had a sinus thing going on a couple days ago that last about two days. Starting yesterday morning he started having wet poops and had about 7 wet poopy diapers all together. It’s slowing down with about 3-4 wet poopy diapers. He is eating regularly but I have no idea what I can give him to help it at least stop or slow down.
