Cluster Feed

Can 9 day olds cluster feed all day and night? Once she stops eating I have maybe 20-30 minutes before she wants to eat again.

If so, when is mom supposed to sleep? How long does this last? I'm exhausted

EDIT: Apparently I am not producing enough milk which is causing her to feed constantly. (She still isn't back to her birth weight.) The pediatrician recommended I take fenugreek for a few days and that we supplement every other feeding with formula for the week to see if it helps.
