Yea, it is happening more. Today, the second feed resembled more a snack despite it being three hours since his last feed. And his day naps have changed. It's harder to get him down.
As for the growth spurt, I "prepared" for it by pumping my breasts regularly a week before, so I would have mroe breastmilk when it happened. The result was he didn't beat my nipples up this time around which is, of course, nice, but on the other hand, it wasn't as noticeable when he went through the growth spurt since I had the milk he needed. I think he had it only because he went through a phase where he feed much more in the mornings and at the four o'clock feed, about 6 or more ounces. Plus, he got bigger. It was just so much smoother that I question if it actually happened.
I think I'll move him to 3.5 hours this week and see how it goes.
Thanks for the response!
