Super fantastic progress, congrats to you both.

What I have learned the hard way over more years than I care to admit is that there are TWO essential things that lead to weight loss success: CONSISTENCY and TIME. Consistency with your diet (meaning no cheating) and then give the body enough time to drop the weight. The body will lose faster in the beginning, and then slow down. It will lose weight faster at some times than others, no matter how good you are in following the diet, so don't get discouraged when that happens. Just keep on keeping on and you'll get where you want. Never as fast as you want it to happen, but it WILL happen.
