I've recently become a father and I do wonder how much US maternity leave (or rather, lack thereof) accounts for your high formula usage.
While my wife is coping, it's still very draining to handle a newborn and pump at regular intervals, even at 10 weeks. If she was in the US and had been forced to go back to work already, she may well have given up on breast milk already.
