I was just speaking with a pregnant mom who was beating herself up for her chocolate cravings and hunger level in general. She's fit and quite slim, but her current care provider (wrongly) suggested to her that pregnant women should gain no more than 20 - 25 pounds...well, that's a topic for another day, but I assured her that she should not be restricting healthy food, as she's growing a human being, so it makes sense that she's hungry!...And some chocolate can actually be good for us. Not only that, but it can help get our brain in the blissful place it needs to be to conceive, give birth to and mother a baby. It's all about the oxytocin!
Plus, doesn't it make sense that experiencing joy is good for growing a baby?
