Well since you will have a young infant at the time OP, I strongly suggest that you do hire yourself a nanny vs. putting him into daycare since a nanny can offer much better one-on-one attention.
Sure, there are a majority of nannies who do not like working w/a parent who works in the home, but there are some who are willing to do it.
My best advice for you is to try to understand that these situations can be challenging, yet they can work out if the parent in the home respects boundaries up front and actually works vs. micromanages the nanny all day.
Also, allowing the nanny to leave the house daily and take the kids out on outings also allows the nanny a nice break too.
Good luck.
