Hai mama! Okay, I understand your worry, switching to fully breastfeeding is a big change and the numbers can feel scary. A few of my mum friends went through the same thing, dan memang susu badan production berbeza dengan formula. Kurang kencing dan urine kuning pekat is actually a sign of dehydration atau supply yang memang kurang, normally you'd expect 6-8 wet nappies a day when fully breastfed. Weight gain 200g in sebulan (I'm assuming?) is on the slower side too, so this is worth checking dengan doctor atau lactation consultant asap, jangan delay. The 1oz from pumping every 2 hours might mean your supply has dropped (maybe sebab stress from work atau latch issue), and baby might not be getting enough even though dia seem content. Definitely see your doctor to rule out any health issues dengan baby, and consider getting LC support for latch and positioning, sometimes baby dapat more milk dengan good latch even if output kecil. You're doing so well juggling work and breastfeeding, tapi in this case professional eyes akan really help. Hang in there!
