At a shopping centre today (during the working day) and I walked past a family of five, two girls both with dummies (one of which looked close to school age). The middle child under parents advice dipped her tiny baby brother's dummy (not old enough to sit up or head up even) in her soft ice cream and gave it to him.
I was so horrified I nearly said something... but didn't as they looked like the sort of family who may have hit me hard in the face. The baby was in a car seat which is one of my pet hates, too.
