Mucus in newborn stool

[Sunshine1509]

Is this just the sign of a virus?
Dd is 5 weeks, taking all formula bottles as normal, her last 3 stool nappies have been quite runny and the last one was just mucus with a tiny bit of poo
No temperature but the rest of the house have a cold so just wondered if it's that?

Is she seems well in herself and is taking feeds, weeing and pooing then I wouldn't worry about the occasional mucousy poo
