My husband wanted me to ask. He thinks it would be illegal.
We have 3 boys. Together they are a handful. I can't drive with a broken arm. I think oldest can be home alone for an hour. He will just watch e enough to tv, happy to have it to himself. He is clever and sensible enough to call us or 999 if needed. We can put youngest in seat of trolly, and middle is fairly docile without older brother egging him on. Would be less hassle if the two aren't trying to race up and down the aisles.
While I typed this DH googled and saw that it's not illegal. Now we're just interested in opinions.
