Working From Home with a Newborn

I currently work two jobs, one full time data entry job and one as a freelance interior decorator. Once my baby arrives I was planning to quit my full time job and just work freelance occasionally as it’s really flexible hours and would allow me to be home with the baby every day. However, my full time job just offered to let me stay on part time (just 16 hours a week) and work from home if I want to come back after the baby is 3 months old. It would be a huge relief for my husband and I to have those 2 days of income guaranteed and not have to rely solely on freelance work.

Any mama’s have experience working from home while also caring for a baby? Is it doable? I mostly work in spreadsheets/email so I would hardly ever need to be on the phone or in video calls. We do not want to do daycare or hire nanny as it is way too expensive.
