4 days RTO?

My firm (top global investment bank/financial services sector) has gone 5 days RTO. I have an almost 11 month baby and they’re okay for me to do 4 days in the office. Here’s my situation:

4 days in the office, 1 day wfh a week. Timings 10-4 (again this is just for me) and remaining hours from home. With a 45 commute in the morning and about a 30 min commute in the evening, this takes me out of the house 9-4.30/5. Childcare situation is a really good nanny and WFH husband (he has health issues and has exception approvals to wfh everyday). Money and benefits are amazing. I’ve been in the firm 10 years and am currently a VP. I’m stuck under a micromanager boss but the firm is probably going to give me a change in team.

Here’s the issue: I feel so SAD leaving my baby through the day and know so many companies out there are hybrid and remote. I’ve tried applying for other jobs but nothing has come through. Also nothing pays me the level I’m getting paid here.

I don’t want to use the word guilt, I don’t feel as guilty as I do sad about leaving my baby each day. I spend mornings with him before I leave for work (about 2 hours) and then evenings once I’m back (about 2/3 hours till 8 pm bedtime)

Wanted to hear from moms who do 4 days or more in the office. How is that going for you? How are you dealing, any words of advice or encouragement? Would love some support because this feeling is just not going away (I started doing the 4 days in Jan this year after working mostly remote since maternity leave).
