My toddler swore today. I think the only place she can have picked this up is nursery - my husband and I don't swear even when she's not around, even before we had her (we're quite prissy, I suppose). Other than nursery, she doesn't regularly mix with people other than her relations who are all of the same mindset as us. It was in context so I don't think it was trying out new sounds.
How can I raise this with the nursery? I'd like to know how they deal with it (so that we can use the same strategy at home) and also let them know that we're not fans.
