we teach our children at home and we have no routine whatsoever our daughter 12 has slept through the night since she was 6 weeks old, the boys 8 and 11 however sleep when they're tired, sometimes they are up for 24 or 36 hours, then they sleep.
but that's a bit chaotic for kids, who really do like routine, but agree - tis hard!
But what if the river leads to a 300 ft. waterfall??<br />
A healthy balance is best
routine is necessary for children. it's also called "structure"
I think you need to strike a balance between the two. Children with no structure don't know what to expect, and don't have a stable enough environment to learn and grow. On the other hand, if kids never experience anything out of the ordinary, they don't develop resiliency.
Routine but with the odd twist is likely most beneficial. Routine has been shown to be extremely important by researchers, however you'd want them to be able to handle the unexpected. <br />
Alternatively, if by "go with the flow" you mean you have no routine at all, everything is unexpected, this is horribly damaging to children. They become a dysfunctional mess.
Routine, it helps them be more organized.
