I don't know what to do or how to react. DM who looks after DC once a week, announced earlier that she caught her playing with her bits in the bath. Told her off, but said its not first time its happened & that 4yo children don't do this and I should be concerned this is a learnt behaviour and that I ought to keep an eye on her. DM has a long career of working with children, so I do usually take her advice, but what, oh what do I do with this? Do 4yo normally do this or not??? Help
