Poos (also in born in July)

For the last three days Aila has had 5 or 6 dirty nappies a day - she'd normally have a poo a day or even miss a day every so often, they are the same colour as before but some of them are a weird consistency like egg White type mucus I called my hv she said that as she seems otherwise ok it's nothing to worry about. Has anyone else had this? She is 6 weeks 5 days old
