If he's around 6 weeks old, yup it's a growth spurt! hehe. Tallon was the same, was a very frequent feeder for the first 3 months, and during growth spurts, seemed to be always on the boob. At around 6 weeks we had a few days where all he wanted was boob and to sleep on me. At the time you feel like it's going to go forever, but before you know it, you're looking back at the time he fed so frequently! Like Tanya said, it's always changing.

You're doing a great job.. sounds like he's growing well! (ps.. that'll slow down eventually too LOL)
