I had copious amounts of milk very early on with DD2 but she still fed hourly. Her little belly was adjusting from the colostrum to milk. They get unsettled and windy as their digestive system and belly adapts. If bub is having wet nappies id be confident in your supply. We had pretty much no big sleep for days 3 - 5.
You're doing a great job, please don't pay attention to your stepmum.
Totally in love with our two beautiful little girls.
