Hi Bathsheba,

When we did the clean catch over the weekend, the sample was pale and clear, and her nappies haven't been dark at all. She feeds every three to four hours during the day (and sometimes once during the night, if she doesn't sleep through), and we've been offering water now that she has started on solids, too, as her poos were a little firm. I'm breastfeeding with a supply line, so she is getting breastmilk and formula, though I have been doing this since she was two weeks old, using the same formula, and nothing has changed there. Would formula cause a variation in urination?
