I feel own parents and in-laws are the best person to take care of your no.1 when you are in hospital for delivery and hospital stay, as they are the second closest people to your no.1. There is no such thing as to afraid to trouble them to help to take care of your little one while you are away. You have to learn to let go too. Unless there are some conflicts between you and them and in this case husband/close friend/close relative is your another alternative for your no.1's care taker while you are away.
Whichever arrangement you have chosen, you should let your no.1 to be familiarize with the person. This includes let the person to handle no.1 for short hours and gradually extend the hours. So that your no.1 will not be in shocked and more settle with the new care taker while you are away.
