Just musing because mine are 1 and 3 but when I was young things were definitely more relaxed and therefore exciting in terms of bedtimes etc I was pretty feral
However this fills me with dread for the future as routines and knowing I'll have an evening keeps me going!! Maybe I'll feel differently when my dc are bigger.
So what happens in your house? Rules out of the window, a more relaxed routine or routine as normal? Have you tried different approaches over the years?
