Query: Didn't work for us

Husband and I bought this carrier when our son was several weeks old, and it was a total waste of money. Ten minutes after being in the carier, our son's legs and feet were icy cold, because the hard straps cut out his circulation. Also in this carrier, all his weight was pressing against his crotch and he didn't like that. My back and shoulders were in pain. It didn't work for us at all. We started using Over the Shoulder Baby Holder sling, and after several awkward tries, we totally loved it.
