It could be a couple different things. If it's lighter colored it could also possibly be a reaction to a food sensitivity. If your little one is also have strong gas pains or has blood in their stool, those are also signs of food sensitivity. If you're already feeding him anything other than breastmilk/formula, you could stop for a couple weeks to confirm.
If it's just the mucous, and the poop has a very dinstinctly different smell than normal, that could be a stomach bug.
Hope that helps!
