It's definitely doable, although ultimately there are only so many hours in a day. You have to choose how and when to spend them carefully, with the support of your partner, as it can place additional load on them. Also, writing code on 4 hrs sleep after night feeds is no fun! Young kids tend to sleep quite a lot relatively (if you're lucky) - so when they sleep, daddy works. It might mean shifting to 2-4 working session per day, somewhere quiet, instead of the more traditional 1 working session per day approach. From my experience defining boundaries/rules that allow for constant, incremental progress on the product while keeping partner, kids and yourself happy is the key. It's very easy to just work all the time and burn yourself out.
