I agree with everyone else PZ, you're doing great! Well actually you're doing perfectly normally :P

Around that time is when I my boobs started to feel a lot less full too. I think I've read you usually have oversupply? So it's unlikely that it's decreased that dramatically, it's probably that it just doesn't feel as full and that's a much different feeling for you. But of course you are still feeding so I have no doubt you're still making the right amount of milk
