<grin> Just remember... in a year or so when you're tired of waking up in the middle of the night to feed your baby, or your toddler has hit a growth spurt (we all, or most of us anyway, get there), EXACTLY what this feels like. Being so hungry that you can't sleep. So hungry that you feel like you're losing your mind/ COULD cry about it, and how lucky you are that you can get out of bed and head to the refrigerator. And then laugh quietly to yourself at people who say this is a "bad habit" to be broken, as opposed to a temporary biological need (growing a baby is just a *fraction* of the growth that our babies do... 6-10 pounds of muscles, bones, organs over 9 months when you weight well over 100lbs of muscles, bones, organs... versus doubling your own weight in 6mo). Contemplate, right now, not eating for the next 12 hours and just have someone rub your back and talk to you instead of feeding you. LOL, as a matter of fact, I dare you to try not eating for 12 hours. ((Does even the thought make you blanche?))
Although, you may actually be craving fat (if so, you're probably building brains and immune system right now, more than anything else). If spinach soothes the crave; it was calcium. If avocado does, or if you think of a steak and you're thinking of that perfectly seared and bubble strip of fat around the edge of it... it's brain & immune system. :)
