RE: How much breast milk should I be producing?
First of all, if your baby is having enough wet/dirty dipes, that is enough to tell you that she is getting enough. It is completely NORMAL for babies to want to nurse more at night, for a while. They have their days and nights mixed up- remember when she was inside and would be all active while you were sleeping? Well, now it's the same, but she's on the outside! It will take a while. What you can do to help that is keep it quiet and dark at night so she will eventually get the news that nighttime= sleep time. But that will take a bit yet.
Some women never leak, squirt, or gush and they still make plenty of milk. So again, if your baby is gaining appropriately (after losing the norm, she should be gaining again and back to birthweight by about 2 weeks or so), and having the right # of dipes, I'd stop the supplement and just keep offering to feed. Many babies have an enormous need to suck for not only nutrition but comfort. And these early weeks are going to determine your supply so supplementing at this point can only hurt your supply that you are building up right now. The best thing you can do is just keep offering to nurse her whenever you think she might be hungry. She can't nurse too much and can't overeat at this age- she will stop eating when she has had enough and switch to comfort sucking to help her feel soothed and secure. You will learn to distinguish her hunger vs. need to suck cues in time, you've only known her for a week so it's still early in the game! There were plenty of times I'd nurse for 20-30 minutes EACH SIDE, DD would fall asleep, I'd put her down and within an hour she'd want to nurse again. Their tummies are so small at this age and can only hold a tiny amount yet they are growing so rapidly.
The first weeks are hard and you will feel like you are constantly nursing, but once your supply evens out around 6-8 weeks and your DD wakes up a bit, it will even out and you won't feel so tied down. For now enjoy this special time!
