Orange-ish bits are sometimes in urine called urate crystals, normally not dangerous just a sign of a little dehydration.
My little one has the exact same thing! I showed a picture to my GP and he said it was fine, just discolouring of the nappy.
We had this and health visitor said it was totally normal
Many thanks :)
Look like a very full diaper which can causes the deep color besides the poop color..
