if you're lady took you to Bristol for lunch with Uni friends and they all had kids present, would you be a bit freaked out?

I'm taking mine on Saturday coz I'm leaving the country and saying goodbyes and stuff and here's going to be here. There's going to be 4 of my friends and 3 of them are going to have kids with them. I'm a bit worried he's going to shit himself, do you think I should leave him in London for the day or will he cope?
