Here's one quote,
"Night time feeds are also important because it is in the early hours of the morning that the hormones that stimulate milk production are at their highest. Your breasts are not a storage facility, they operate on a supply and demand basis, the more your baby suckles, the more hormones are released that signal your body to produce more milk, so the night time feeds stimulate even more hormones which set your body up for the day ahead."
Supposed to be less important after like 3 months.
