DH was a chronic thumbsucker into his teens. He had to have the appliance with the spikes on the roof of his mouth to break him of it, and it really flared out his front teeth (so badly he almost had to have head gear!) He wasn't EVER sucking his thumb when he was awake, but he would subconsciously do it in his sleep and wake up with his thumb in his mouth! Sooooo.... I was a mean mommy when my babies put their thumbs in their mouths. I swapped them out for pacifiers, but then, they didn't suck on THOSE past 3 months, so who knows if they still would have sucked their thumbs?
When you're ready to get her to stop, there's a nail polish that tastes TERRIBLE that you can put on her thumbs. It broke DS1's nail biting habit in a week.
Sorry to hear about you ladies and your morning sickness. The only thing that ever helped me was exercise, and it only delayed it. I'd feel pukey before my workout, absolutely fabulous 5 minutes into the warm-up, and then I'd vomit as soon as I got home when I was carrying DS2. I totally get what you mean about the MS and gender, Longing. EVERYONE around me told me DS2 HAD to be a girl because I puked until 20 weeks. The real salt in the wound was still having MS after I found out the gender at 18 weeks. Ugh!
