I can't take any credit for this tip. My sis in law told me when I was pregnant with Baby Sister.
If you are going to a fast food place to go in and eat or play on the playground, order at the drive thru while the kids are all corralled and then go inside.
I thought this was a pretty smart tip! I haven't used it yet but I am sure I will one day soon! I try to avoid fast food places these days but sometimes it's easier to grab something quick for Big Sister, who seems to always be starving.
