Is it bad I started pumping already. I just want to make sure I have enough supply for the baby.

Yikes you could go into preterm labor, I would stop pumping. Like others have said, your baby only needs a tiny bit of colostrum the first week, newborns stomachs are the size of marbles. I was told to nurse every two hours from the start of a feeding session (my daughter would nurse upwards of an hour in the early days) even if I had to wake my daughter. I did that until she gained weight and our pediatrician gave the ok to start nursing solely on demand.

The baby's belly is so small at birth he/she will only need the tiniest bit of milk. It will only be about the size of an almond. I wouldn't pump anymore.. As already stated it can put you into labor too. My little guy was born 9lbs 9oz and I EBF... My milk didn't come in for about 4 days and he was perfectly content with what he was getting, I never had to supplement

Anything you do to try and increase supply while pregnant has no connection to how much you'll produce after baby is born! You will have colostrum after birth, and that's all baby needs for the first few days of life! After about 3 to 5 days, THAT'S when your milk will come in, and you'll most likely start feeling engorged. Just feed baby often, on demand to keep supply up. The more baby feeds (NOT pumping, it does not stimulate as good as baby does), the more it sends signals to your breasts to produce milk! So the key is to feed often for however long baby wants for at least 4 to 6 weeks, then if you are going back to work and need to introduce bottles, that's the time to do it. Pump just as often as baby would eat, and get baby to the breast whenever you're together!

They typically don't recommend pumping before birth due to the importance of the colostrum. It's only produced in small amounts. Also, if your not 37 weeks or later, they don't want you to go into preterm labor

The problem with pumping is it can cause contractions so you need to be extremely careful, also you're pumping your colostrum which is very important for baby the first few feedings

I don't think it's too early. it can be frozen and used later, unlike formula.
