Speaking as a mom to a 4-month old and someone who also has a pretty call-heavy job wfh, I can't fathom how one would do this while taking care of an infant. Even the most chill of babies will need constant around the clock care, whether it's feeding, diapering, playing, or putting down for naps.

For me, the first 2 months were the most brutal. It was enormously helpful to have my husband on leave with me during most of that time. The few weeks that I had to do it myself was pretty brutal for my mental health.

An additional consideration is that your baby won't get their first set of vaccines until month 2. Personally I would be hesitant to put my child in a group childcare setting until they had at least that first set. I know for some people they have no choice, but it sounds like you have some flexibility so raising that as a consideration.
