Hi ladies. I have to make a very difficult decision about work and my boss wants an answer tomorrow. I have two options for my job that would either stay the same or change when I return from maternity leave. This is our first baby and I'm really conflicted. My husband works M-F from 8-5. My options are:
A) keep my current schedule, M-F from 8-5. Baby would be in daycare full time but in the evenings we would all be together. 
B) take the new position that is 2 days per week from 8-5 and the other 3 days from 12-8pm. This would allow 3 mornings a week when I could be with baby but his dad would pick him up at 5 and they'd be alone until 8:30. Basically it keeps baby out of daycare 12 hours per week but means we do a lot of parenting alone. 
Which would you choose and why? Thanks so much! I'm really fretting about this decision!
