at my house we do bath then story and i allow my dcs (6 and almost 3) to read for 10 minutes after i leave the room. but this isn't what happens. they get in and out of bed and take more books from the shelf, start playing and carrying on, jumping around the room and sometimes wreck it. ds2 will come down the stairs crying because ds hit him. i will take him up, get ds1 to apologise (whether deliberate or accidental) and tell them both that it is lights out and they must go to sleep. they both agree but as soon as i am downstairs again they start fighting. ds2 is on way downstairs crying as i sleep crying that i turned the light out and he cant read his book. i used to not let them read after i left and i turned the lights out but they misbehaved anyway so i thought giving them 10 minutes wind themselves down would help. it hasn't.
what do i need to do?
