At 2am this morning I put 2 & 2 together. Skye is not an impatient night owl...she has lactose overload due to my Jersy Cow breasts. I simply produce way too much milk so she never gets to the proper fatty stuff at the end of the feed - she's just loading up on sugary lactose. Bugger...it's taken me two weeks to figure it out, I hope I can fix this problem. The good thing is at least I understand the problem now and I don't resent the hours of sleep I'm losing.
