Perhaps to be safe you need your special underwear for a day out. But you can wear your big boy undies over the top

@Littleivo What ever makes you comfortable on your trip over here, little guy. Perhaps the robots on the plane trip and you change afterwards. Forecast says 22 degrees so dungarees are a perfect choice! (they always are)

@Littleivo why not both ? 🙈
either the big boy underwear above the little one to hopefully hide he's still having daytime accidents.
or the other way around so he can still have accidents and be constantly reminded how a baby he is with the wet cotton against his skin 😇
