As long as you keep getting up at night, so will the boys. Learning to sleep through the night, is a developmental skill just like walking, using a spoonor a cup, brushing their teeth and toileting. You are the parent and you are the one to set boundries, like staying in their bed at night. You don't let them hit or bite. There are many different approaches to getting to the goal of sleeping all night, but consistancy is the key to success.
