Baby poop!!

I know this question has been asked before so sorry! My 4 month olds poop has shifted from wet and seedy, to goooy recently. I didn’t think much of it (he was EBF at that time)

He is still EBF but I mixed a tablespoon of baby rice in with a bottle of expressed breast milk about 3 days ago, and again today. I noticed his farts now smell which I assume is normal 😂

Anyways, his last two poops have been really thick, think soft serve ice cream....and kinda an egg-whitey texture (in that it kinda keeps its shape between your fingers)

Is this normal? It’s a yellowy colour so that’s good. Just don’t know what to think of the thickness and texture.

Thanks!
