I think you could go the nanny route as long as you do it "right."
By right, I highly suggest you try your best not to step on each others toes.
Let your nanny have as much autonomy as possible + do not micromanage her during her shift.
Let her take the baby out during the day for outings and walks, and if you hear the baby crying or anything, try to stay out of the situation and let the nanny figure things out on her own, unless of course she asks you personally.
These situations can be tricky, but I believe they can also work out if the parent can set boundaries and not overstep them.
The parent needs to focus on her work, and let the nanny focus on hers.
Of course, the nanny may feel like you are watching every move she makes and listening to every single sound being made, but if you honestly stay out of their way as much as possible, then I truly believe a set-up like this can work.
I do not think a daycare situation would be feasible w/a young baby because your baby will need the one-on-one attention that only an in home nanny can provide.
Hope this helps.
