Hello - have 3 dcs - baby, 3.5 yo girl and 7 yo boy...The two eldest usually have a bath together - both are scared of showers..anyway, they've taken to lying on top of one another and making free and easy with each other's bodies..usually just willy and bum jokes, so innocent fun but then the lying on one another seems a little inappropriate..I feel like the perve police standing at the side calling: 'get off your sister' 'no touching' etc - my dh says we have to get them to bathe apart from one another but they're really not keen. Any tips? Any particular age they 'shouldn't' bathe together?
