Post kid fork

Hi! So wondered if I could get some hive mind wisdom.

We are a couple (one end 30s, one mid 30s) who just had a kid. It’s honestly wonderful such a blessing but I (the man) am unsure about how we make sure that my partner stays happy as we progress through parenthood.

Career and business has always been my partner’s life - she works crazy hours on her start up and her whole network is entrepreneurs. I lucked out with successful job hopping and do what I love now. But that means realistically we’ve been living this life for quite a few years of 7-7 out of the house (or just in the home office if remote) plus a late night and weekend work fairly regularly. We both love what we do, we earn about the same give or take and work similar hours.

I don’t think this arrangement is going to be realistic once mat and pat leave is done and we are both back at work full time - what do others think? And how to have the conversation with my partner? Feels like a fork where one or both of us could end up resentful - tips from others who have navigated welcome!
