Wow, I didn't realize your ds1 was born at 33 weeks. That must have been really hard for all of you.
I don't know much about early engagement with subsequent pgs, but I was amused when I read your post because I had my 32 week check up today, too, and I was basically probing my mw for when this baby will (please!) drop. I have so much reflux and trouble keeping my food and water down that I am so eager for it to drop. But, I guess I should just happily wait.
It sounds like your stress hasn't eased much. DH must still be job hunting, is he? Hugs to you!
