At some point every morning I say, "If you miss the bus, you won't go to school. You will have to go back to bed and stay there until Daddy gets home." It's an effective way to motivate the girls to get out the door in the morning.
Today we were in the "must get out the door now or miss the bus" rush when the tree service showed up. They are taking down and moving some trees for our patio project. We knew they were coming; we just didn't know when.
My husband ran outside to talk to them and I kept trying to get the girls ready. When it became clear that we were about to be late the brunette twin said, "To be clear mom, if we're late it's not our fault. It's because Daddy and you went to talk to the tree guys." The blond twin chimed in with, "Yeah, so if we miss the bus, you have to drive us to school. We're not going to get in trouble because it's not our fault."
They made it to the bus on time, so we didn't have to drive them to school. I have to admit that I admire the way the brunette twin set the boundaries. She'll stand her ground when she thinks it's necessary.
