I always get people saying to my ds, 'You don't want that dummy, I can't see your lovely smile'. I just say to them, 'He does, he loves it'.
At first I used to feel like apologising for the fact that my son had a dummy, and used to say that I hated him having one, but it stopped him moaning. Now, I just know that it makes him happy, so I try not to let other people get to me.
My mum insists on it being taken out if she is taking a photo of him! It does annoy me a bit, but then it is her camera I suppose.
I too hate people touching ds when we are out. I have no problem with then commenting on his 'big blue eyes', or that he is very smily etc, but what makes complete strangers think that they can touch your child? I smile at children in shopping queues, and wave to them, but would never dream of touching them, and would never have done before having my own.
I know that they are all probably nice, decent people, but it gives me the creeps. Does this say something about the world we live in, when we can't trust anybody, or am I just overprotective???
