Confinement food worries

Hi to all experienced moms, First time mom here and was wondering a few things for confinement. I do not have any help as both my parents and in laws are working. - When do you start confinement food? Do I order it for the day after I’m discharged or a week after? - how many days of confinement food is enough? 20 days enough? #advicepls #firstbaby #bantusharing #pregnancy
