my mom did this with all her kids
she had five kids and she said she would have gone crazy if we didn't take a rest in the afternoon
we called it quite time and it lasted for a hour and a half everyday
we could read or play in bed by ourselves (so we wouldn't fight)
but no talking
i actually have good memories of some of the great books i read during that time
and i think it's good for kids to spend sometime by themselves to think
it also teach to be respectful of the parents needs which i think is important
and it could help you be a better parent because of a much need break
anyway i plan to try to do this when my girls are a little older
as they still take naps now thank God
