Green poop

I think it is normal but I just wanted to check 🙂

My baby poop was always yellow like color but now it is green.

We have started solids, like purées carrots, peas and rice with banana.

Does that mean that from now on his poop is like adults? Depends on what he eats?

Also he did have diarrhea for three days? It is better now, not so watery. Could that be from starting solids as well?

Thank you
