The booster seat label is LAW

I was coming home this evening at about 7.30 pm with both girls ready for bed. handymum was staying with her mum for a wee bit.

Miss3: Are you going to carry the baby into the house?

Me: Yes.

Miss3: I want you to carry me in too.

Me: Ok. I'll carry her in and then come back and carry you in.

Miss3: You see this label? (pointing at a safety label on her booster seat). It says "don't leave child in the car alone". That means you should carry me in before the baby.
