Hi... something popped out at me from your response. You say he ate very frequently in the evening - supply is at its lowest at that period. I guess by now he's almost 6 months old? Abby just went through a 6month growth spurt and boy was it a doozy. The worst one by far! I just had to ride it out, but it sucked for almost a week. Seriously, the growth spurt and the extra activities CAN be a cause of frequent night wakings, and we've been going through them for almost 3 months. That's right. I'm not saying that yours is going to go on for so long. But we're finally getting a handle on it, so there is an end in site. Anyways, just thought I'd let you know that you're doing great, even though it may seem that nothing is working. Keep at it, and you will see results.
