My twins are 5 months old and slept 12 hours at night from about 2 1/2 to 4 months. But, for the last month they've started waking at night. They got sick and were going through a growth spurt but we are going on a month now and I think the issue is this: I think I make just about exactly what they need for the day and if they start eating in the middle of the night they drain the supply early and by the early evening they've depleted most of the milk. If they don't eat in the middle of the night there's enough to last through the day (I realize you continue to produce but you get the jist, I have a lot in the morning and by the last feed still have enough to satisfy them). I tried to get them to not eat during the middle of the night so we could get back on track, and used pacifiers. One of them made it and by the 5 a.m. feeding her diaper was barely wet. They used to have sopping wet diapers in the a.m. even after sleeping 12 hours. So, I know it's a supply issue. I tried fenugreek with my son and I got horrible migraines from it. Any other suggestions? I really don't want to supplement but I am going back to work soon and won't be able to function if I'm up 4-6 times a night for an hour at a time.
