Query: Excellent pump for 'round the clock use!

My son is 11 days old now and I started pumping about a week ago because he doesn't latch on well. This pump is excellent! I can get as much as 6 oz. in about 5 minutes of pumping! I highly recommend this pump. I use it for every feeding and in between and my supply is growing! I also like the Avent bottles. My son barely has to burp when I use them, and there is no spitting up!
