Premie mamas

I had my son at 34 weeks on Saturday the 6th, and I've been pumping every 3 hours and getting very little colostrum. The nurse and lactation nurse assured me that it's normal since he was born early that I'm not producing much, but I was wondering about when did your milk come in? I want to give him the best start possible! Here's a picture of my perfect little guy, Dax Evander 😍
