You end your requests or commands with "OK?" This is an easy one. If "no" is not an acceptable answer, then don't ask if they are OK with it. "It's time for us to start getting ready to leave. You have two more minutes to play." Period. You can do it.
I can not wait until my sweet Tiffany gets here. You never know how much you can truly love someone until you have a child. Your love for them begins the very first day you find out they are going to be entering your world in only a few months :)
