Confinement meals

Hello hello! My husband wants to order confinement meals for me instead of getting our confinement nanny to cook due to the following reasons: 1. Grocery money would end up about the same as confinement catering (his friend say one). 2. Its alot of work for the nanny to prep all three meals and clean up when the time can be better spent at taking care of the baby. I have no idea what groceries would cost $300+ a week actually. So I really don't think it makes economical sense to cater food when we have already engaged a nanny. Any advice?
