Hi all, new mum here who panics about everything! Our little boy was born 4 weeks ago at 35 weeks. He had a very odd nappy today, half yellow, half brown, quite loose and smellier than usual. I have a photo but unsure if you'd want to see! Any advice would be welcome. He's had more spit up than usual the last few days and I've had a cold, I'm wondering if I've passed on some virus to him? He's feeding well, if a bit gassy but that's normal.
