Hoping for some advice on managing formula feeding, especially out and about. Intended to BF my 2 week old LO (FTM) but it hasn't worked out yet, so I'm pumping and formula feeding. How do you set up for going out and about with formula? Or for overnight? There are so many rules on timings and temperatures, I'm feeling a bit stressed about getting it wrong so have been relying on ready made, which is obvs very expensive. So much advice available on breastfeeding but not much on formula!
