Kids can always take more. There's always something you could be doing to help them, to improve their future prospects, to make them better-adjusted, give them better nutrition, give them some help with making friends or maintaining relationships, et c. It's absolutely necessary to say "no" to that stuff pretty often. They can be "the priority" as long as that allows that a good deal of the time they actually won't be. It's also not the case that one must only make that trade-off when there's some Greater Good in it for the kid(s). You don't give up your life because you have kids. The notion that you should is very modern and is still not typical in a ton of (non-US) cultures.
