The real question is WHY has my supply crapped out? After much discussion of my history, it becomes very clear: really really bad, conflicting breastfeeding advice. After being sent home from the hospital supplementing and tube feeding, overcorrecting with pumping, overcorrecting with block feeding, low dose birth control pill and cutting out night feeds, it's obvious why my milk has struggled to keep up. It appears that even my mini pill is affecting my supply so I will be dropping that ASAP. I now realize why Matthew seemed suddenly "colicky" at 6 weeks: he was reacting to a drop in my supply. It's probably the reason for all the nightly wake ups. It's probably the reason for Crabby McCrabberson showing up every afternoon and lately every morning.
So we have another piece to the puzzle. Now I just need to make an appointment to get a referral with a pediatric allergist and wait for my follow up appointment at the breastfeeding clinic. Hopefully at that point we can make a plan for how to proceed when I go back to work. Fingers crossed that we get some sleep REAL soon!
