My wife is a startup co-founder and she started up when our daughter was three. They were bootstrapped initially and now have raised a couple of rounds in 5 years. Our daughter has grown up into a little person with a very kind character and promising developing talents. So I'd say very doable amd some enablers are: 1. One partner should have a steady sufficient income to keep head above water with sufficient buffer for unexpected expenses. I've had friends who tried it single income and they had to pack it in 2. You need to keep a schedule where you'll be there for some sufficient time in the day for the child or the child will start missing the parent and act out. In my wife's case, she usually takes three quarters of an hour break when our daughter comes home from school and also puts her to sleep at night during school days. During weekends, she usually spends Saturday morning exclusively with our daughter. During vacation weekdays, she spends a couple of morning hours (time zone benefits)

So I'd say go for it! Best of Luck!
