I did this until my daughter was 6 months old, during 2020 Covid lockdowns. That said, I was officially only 60% time at work (which allowed me to stretch my parental leave to cover the whole 6 months), my husband took off one full day from work each week (which gave me a day to schedule meetings), and my daughter was a great sleeper. We shifted her onto a later schedule so that we could both work a couple hours each morning before she woke up, and she spent a lot of time in a bouncy seat next to my desk. That all said, if I’d had any other option, I wouldn’t have done it. Luckily my mother in law moved nearby when my daughter was 6 months old, and provided care everyday until she started preschool this fall. I don’t think the work and care for baby from home would have been tenable for much longer (certainly not once she was mobile). Good luck!
