how time flies. wow.
I wouldn't worry about laying on the weight. I am a big gal too and I gained 1lb for every week, which my OB said was typical. How I envied those that didn't put on any except what the baby weighed and it's "baggage" LOL
If you are hungry, I'd eat eat eat as you feel. Because I bet you anything, the last 2-3 wks of your pg, you'll be eating like a bird
Maybe your body is working hard at fighting some cold bug or baby is having a growth spurt and needs the extra rich blood (heck, I have a million excuses to eat. lol)
Enjoy these last few weeks. Soon you'll be holding her and nuzzling her every chance you get and won't be able to let her out of your sight
I hope you post a pic of her in her onesie.
