My last point
I doubt a 3 year old even knows what Formula is - my DD doesnt walk past the baby aisle and look up at the tins on the shelves and go oh look formula Thats what I give Baby Annabelle
LOL, today we were walking down the baby aisle of the pharmacy warehouse place. We walk past the nappies and Jack points to them and says "for babies". Then we walk past the formula tins and he points and says "for cats"! I'm not quite sure where the for cats comes from, but I guess it shows your point Caro.
