I have found that long hours at work or work that makes you very tired (or is very engaging) are bigger obstacles then kids. If the day job is easy, then you can have own projects in the evening. If the day job is tiring, then you cant.
Kids require your time, but if you share duties with spouse, that alone does not make out-of-work projects impossible.
