Is this standard for junior infants

That's a strange kind of ignoring.

What is wrong with teaching body parts? Teachers would prefer not to be discussing it too but they are required to do so and they are under no obligation to inform parents of what they will be teaching on a given day. Some crazy comments in this thread.

It's interesting to explore the origins of the terms ."You know, children, penis comes from an old language that nobody speaks any more called Latin. It means tail, any kind of tail.Vagina means a covering made to hold or contain something. It was Latin for a sword holder. What do we call that in English? With this approach there is less likelihood of unhelpful giggling and embarrassment in later years.The makey uppy names for body parts are silly and unnecessary.

What percentage of parents actually do provide it though?

It wasn't a turn, the thread was always going this way.

Oh right, I honestly didn't see this coming. But you're way off & on the verge of paranoia here.

Teaching boys and girls the proper names for their body parts has nothing to do with transgenderism. In fact by teaching them proper & appropriate nomenclature it's differentiating the sexes, not confusing them.

Now I see why it's sometimes up to teachers to teach kids stuff they should know from home.
