Just thought I'd let people know what happened to me today, partly to let off steam and partly to warn you. I was on my own with my baby in Boots Manchester city centre baby change room. A woman came in on her own without a baby and started leaning over the baby and asking me about what she eats. I moved towards my baby and she moved towards my bag. She told me to carry on changing her and continued to circle towards the bag whilst repeating the same questions. Once I really knew what she was up to, I picked my baby up, stood in front of my bag and said 'Well goodbye' loudly to her. She then left.
I gave a very brief description of her to the manager, but felt annoyed that he didn't want to know anything more. After all if she'd tried it once, she could well try again.
Anyway, I'd suggest being careful in situations like that, I never expected it to happen and was lucky not to get caught out.
