***Just an FYI, measuring what you pump does not give you an accurate amount of what the baby gets while nursing. A pump and a nursing baby work in different ways and get different amounts out in the same length of time. Babies are typically much more efficient than pumps.
Also, I am really shocked at the amount of people who let their babies CIO, or who say their docs recommend that. Everyone does what works best for them, their family, and situation, but CIO is not something that works for us. JMO

It sounds pretty typical of a breastfed baby, and age appropriate. If he is on the smaller side, you don't want to restrict those calories. It may be a growth spurt, or if he is learning a new skill it may disrupt his sleep. 6:30 is a pretty early bed time, you may want to try pushing that back a little to see if he will sleep longer/better. I bfed all 3 of my kids and it took a long time for them to learn to sleep all night. It was fine, they are only little once and I now miss that special bonding time I had with them when it was just the baby and I up in the middle of the night.
