I think my son is going through his 3 mo growth spurt. He is 11 weeks today. The other night he slept from 11:30 pm - 7 am and I was surprised in the morning that my breasts did not feel very full. Since then he's been nursing every 2 hours or so for the past couple days and I haven't ever felt very 'full'. He still seems to get what he needs and is on exclusively breastmilk. Is this cause for concern or does it sound normal for the frequency that he's eating? This is around the time that my first son and I had to stop nursing due to a variety of issues so I want to make sure this time around my supply does not become an issue.
