Hi Mzroyalty:
First of all, you need a routine with your children.
Get a appointment book with 5 columns. A column for each of you.
Put in the routine for each of you.
Look at it with your husband and plan your time together.
Secondly, You can put your three children in one bedroom.
Go through an orientation with the children about what they are
expected to do when in their room.
Thirdly, You need to enforce the rules. If you have a problem doing it, take some lessons from a parenting advisor. Note: if you don't learn to discipline your children, the schools and police officers will have no problem doing it for you in the future.
Fourthly, You need to set a routine up to go to Sunday School and Church. The children will learn to self-govern so your discipline will be enforced by what they learn in Sunday School.
Good luck.
Thanks for asking.
