With Izzy my milk didn't come in til day 5, and this time around I was determined not to have my little man topped up with formula or me in tears so on day 2 I fed him 3 hourly on the dot both sides, morning and at night we expressed if he slept longer and I also expressed after EVERY feed. It was tough going and my nipples were a tad sore but the midwives really helped me and we syringed those 2-3mLs to my little man after the next feed which he loved. It really seemed to help because on the night of day 3 my bb's started to feel a little fuller, and by the time I came home on day 5 my milk was pretty much there. It took nearly a week to get that OMG full feeling but it came in enough that he was satisfied and topping up wasn't needed. I also drank HEAPS of water and I mean heaps particularly during feeds. HtH Good luck hun! Lots of great advice here!
