My baby is 12days old. I was told not to let more than 3hours pass during the day to breastfeed again, from the start of the previous session.

However, she kind of cluster feeds during the night.

Example being that she nursed a total of 30mins this morning starting at 05:00, taking short feeds of less than 6mins at a time with breaks inbetween. She fell asleep at 06:35.

So when do I actually have to feed again, or do I just go by her cues? During the day she does nice long sessions, switching to the other breast and then falling asleep.
