Re: Supply and ong streches between feed
I think the conservative course of action is to continue to wake the baby at night until he's 6 weeks, and then let him sleep long stretches if he likes. During the day, I would continue to wake him every 2-3 hours, because the more calories a baby takes in during the day, the more likely it is that he'll sleep nicely at night. (No guarantees, of course, especially once teething starts!)
Since you're nursing now, instead of EP, you don't have to worry about being short. The baby will be able to maintain your supply at the proper level by nursing more if he needs more milk, and going longer between feeds if he needs less. This beautiful system works even at night. Your body is surprisingly trainable, and when a baby sleeps long stretches your nighttime supply will decline but your daytime supply will stay adequate.
Babies generally start to wake up more between 3 and 6 weeks. It sounds like your little guy is still a sleepy one, so I see no harm and lots of potential benefit in continuing to wake him.
