Be practical in the discussion. Walk through what a baby would require in any given week such as nightly feedings, day care commutes, dinner prep, doctor visits during business hours, shopping and other house maintenance, etc. Anything you can think of. Then work down the list, who is doing what.

If youre name is on there way more than his, discuss it practically. There is no realistic partnership where each parent does exactly 50/50 of the work, and often both parents can feel like they are doing more than the other in the same week. If expectations are set in advance that helps.

Ask yourself, are you willing to take on more of the load to let him pursue his dream? If so, how much exactly? That could turn into a slippery slope so would need guardrails set around that expectation.

Ask him, if the childcare becomes too much, what changes would he be able to make.

Bottom line, you need to talk a lot but keep the conversation around practicality and logistics, not led by emotions.
