Stay Home Mom

I have been a career woman for 20 years since I started working at the age of 19. Now I am 40 years old and have my first baby this year Jan 2020. I have been having this dilemma, either go back to work after baby is born or be a stay home mom. Somehow the current virus situation kind of make the decision for me. The competitive job market... the uncertainty of the safety at workplace and infant care centre are some of the reasons that make me decide to stay home with my baby. However, I really don't know how to feel fulfilled being a stay home mom. At the back of my mind, I fear that I may get obsolete. I hope some stay home mom out there can give me some tips on how you go through each day at home. How do you keep yourself stay relevant? What else can you do besides taking care of baby, do housework and cook. Basically, I feel lost and feel stuck at home. I just don't know how to be a stay home mom and feel happy about it. Maybe because I'm so used to working.
