Hello, I'm nearly 20 weeks pregnant with boy/girl twins and at the 18 week ultrasound they couldn't see my sons legs. I had another ultrasound yesterday to try and confirm it. They think that his legs stop just after the knees. We're obviously in shock, but have been amazed by the support we've received. Luckily my daughter has no defects and is completely healthy. I was wondering if anyone else has children with congenital limb defects? And how you coped..? Any advise would be welcome!
