when,

you walk around a supermarket exclaiming loudly and excitedly "ohhhhh milk nom nom nom" ........ "yes, doggy on the tin"
you survey shops quickly to determine if they are pram friendly
park as far away as you can from a main entrance so you have PLENTY of room to get a screaming baby in/out of the car without worrying about knocking the paint off another vehicle
you never eat a full meal by yourself..... little fingers helping themselves to your plate
