There's no indication that the children are robotized, at least in this film.
The idea is that not only are the Men so talented that they create robots 'so real that the kids don't notice', but its another indication by author Ira Levin that the mom exists only on a *surface* level to the kids as well as the husbands!
For example, in the novel, Joanna comments to one of the kids of a newly robotized woman:
Joanna (sadly): "I can't get over how much your mother's changed!"
Little Boy: "I know! She doesn't shout any more, she makes hot breakfasts...I hope it lasts. But I bet it doesn't."
So the kids, like the husbands, don't see their spouses/moms as real human beings.
They're just to serve them.
So they'd be unlikely, at least for some time, to be alarmed by any changes in them.
I'd say this cloud is Cumulo Nimbus.
Didn't he discover America?
Penfold, shush.
