Its a joke from the
Simpsons where the Marge flirts with overly obsessives smothering of her children (in a single episode) and she dictated every whim and action at every second. Helicopter mummies in theory hover over their children 24/7 and even do the thinking (homework as well) for the child. I'm not sure if I'm describing it in the manic way it was described in that one episode.
As for small children? I guess I can hold my own and I'm not deathly allergic to their kind.
