Pale poo - pic included

Has anyone noticed/had their baby’s poo go paler for any reason? It’s a pale yellow/beige colour and it’s been like that for around a week. We’re currently weaning off of breastfeeding so she’s having more cow’s milk than before and she’s also on the mend from a chest infection and is still phlegmy - not sure if either of these would have anything to do with it? She’s absolutely fine in herself other than that!
