And ditto Bug though.
Not saying this is you.
But I have seen/known some Moms, that ALWAYS have their baby in their carrier and always wearing them.
The kid, hardly ever touches the ground.
And is never in a stroller.
I never used any carriers with my kids when they were babies.
They just HATED it. And I had had all kinds/types/brands which I got as gifts.
