Did your infant cluster feed? I assume it happens mostly in the evening, just nursing constantly until they finally fall asleep for hopefully a long stretch? And, often enough that it's a pattern not just a random night. Also I think this happens with formula fed babes too I am just not quite sure how that works.

I ask because i thought virtually all babies go through a period of this, but my friend who just had her second had never heard of it. Wondering if it's as common as I thought.
