My wife (34F) has gained a lot of weight and it's really cute.

My wife is 34 years old, 5 feet tall (152cm) and her weight has been 64 kg (141lbs) for a while. She was a little bit thin for her height and frame. She has a big appetite and eats a lot almost all the time. Due to this, she has gained 3-4 kg (6-8 lbs) per month and her weight is 76 kg (168 lbs) at the moment. Her waist circumference and belly have increased significantly. It looks really cute and nice :) I am happy with her for gaining weight. I want her to continue to gain weight.
