julienuce,
Chill, baby, baby, chill!
And CONGRATS!!!!
I've only got two kids, so am less experienced than you so far there, BUT...
I went from 172 before pregnancy to finally settling at 192 5 months after delivery (was wayyy up over 200 during the last few weeks of pregnancy and right after delivery--about 40-50 pounds gained in all). As you can see, a very high weight-gaining pregnancy. However, I lost ALL that remaining 20 pounds of baby weight, super-easily, with SLD once I discovered it at 5 months postpartum and breastfeeding. All 20 pounds of baby-fat gone, within about 6 weeks on SLD. I only have difficulty losing the PRE-baby fat on SLD; getting back down to 172 was easy.
So, I bet you too can EASILY lose whatever post-baby weight comes along. I don't think our bodies particularly care so much to hang on to it. And well done knocking your pre-baby weight down so far before the pregnancy started! I bet that will help you out a ton!
As far as reducing weight gain during pregnancy, I would ABSOLUTELY put your and the baby's nutritive health first!! There is so much that happens in the womb to the baby that is mother's-nutrition-determined, and it can't be undone later! It sounds like you are doing the right thing by making sure you get recommended doses of everything. Prioritize this first! And
then if you find you're simply eating waaaay too much or not making good choices, you can use SLD as a pregnancy-nutrition-assistance method, to help you keep to an EXCELLENT pregnant-lady diet.
So don't worry about the post-baby weight. I'm a lifelong naturally-expanding-fattie despite eating very healthily, and am from a family of grand fatties just waiting for our famine to come along and leave us the sole inheritors of all the village property after everyone else died off. Yet I STILL lost all the baby fat on SLD, no problemo.
Keep us updated on your progress with your wonderful
BABY!!! And take care of her/him and yourself! You'll have all the time in the world to easily lose that fat later, and the results of the nutritive choices you make now cannot be made up for later. Have a great pregnancy! (That's an oxymoron in my experience, but maybe not in yours.

) And I bet SLD will be a wonderful assistance if you do really start crazy-eating!
With much mommy-to-mommy love and support,
Ann H
