Pumping in private

Is it twisted that Tobey sometimes see me using the breast pump? It's not as if I'm saying, "Tobey, come watch mommy pump breast milk!" It's more like I gotta pump and Tobey's awake. He can identify the pump by name and knows it has to do with baby's milk. And at this age, I don't care if he blurts out, "Mommy pump!" to friends or family because he's still at an age where he can still look cute saying stuff like that.

But say I'm still pumping in 6 months and Tobey is more articulate. Or say we have a third and Tobey is 4 or 5 years old when I need to pump. At what point is it just weird and twisted that the older children sees mom pump? Or is it already weird? I suppose I can put Tobey in the playpen and pump in private but that kind of means pumping in the bathroom again. Hmph.
