Not only does lack of sleep affect mood, it also interferes with losing excess baby weight, since the body holds onto fat stores when it is sleep-deprived. The diet solution is to drink lots of water, eat regularly, avoid caffeinated beverages (coffee, tea, energy drinks, chocolate, etc.) after 12 noon, limit sugary processed foods, and eat a light, low-fat dinner, since heavy meals interfere with a good night’s sleep. Until the baby is sleeping through the night, take advantage of her doze time and take a nap, too!
