Is WFH PT possible with a newborn?

First time mom here so please be nice. My little girl is 10 days old so I’m a very new mama as well.

My husband and I were planning to send our baby to daycare at 10 weeks. I work from home and only get 6 weeks maternity leave but my boss said I can “slow roll back in”, so i just chose 10 weeks because 6 seemed way too early.

I work for a small company so the management has been pretty flexible and understanding. I’m salary and my job is in marketing and social media so I do have the benefit of working very flexible hours.

Once our daughter was born, my whole outlook on daycare changed. Now I just think 10 weeks is too soon for daycare. And I just can’t imagine parting with her while she’s so little. I’d like to keep her home until 1 year if possible. Even after 6 months home maybe I’d feel more comfortable.

My idea: I will cut my job in half and work 20 hours a week vs 40 hours, and keep the baby at home for the first year. I’ll work 4 hours per day as I have the time (As long as my boss approves this).

My question: is this completely out of the question? Is it too difficult? We also have a dog but we have a fenced in yard so that shouldn’t be too much of an issue. My husband works in office T-Th and at home M/F so he can also help on those days.

Moms that work full time and part time from home, is it possible? I know it’s not going to be easy by any means, but it’s a sacrifice I want to make to have her here with me as long as I’m able to.

Please help!
