My dd was diagnosed with talipes at the 20 week scan. I was told to consider her at very high risk of a chromosonal or genetic abnormality, and offered a termination. That was it: no further discussion, no counselling, not even a leaflet. Oh, I was also told the talipes was moderate-to-severe, and that she would never be able to dance, or run a race.
dd was born with talipes that scored extremely low in severity (1 on a scale of 1 to 6). She was referred for Ponseti treatment, but after a couple of weeks the consultant felt she would prefer a 'wait and see' approach, so the boots came off and she was just kept under review for a couple of years.
She is now 5 and has totally normal feet. She does gym, plays ballet, swims, and runs races.
What I learned, from the very lovely physio who treated her, is that it is very hard to diagnose in utero the severity of talipes, or to differentiate between positional and genetic. Talipes is a soft marker for chromosomal or genetic abnormalities but not, obviously, if it's positional. If it really is positional, and they're confident of that diagnosis, you are at no increased risk of any other problem. So i would suggest that either they are not confident of that diagnosis, or they are indeed covering their backs. That physio was furious that I had just been offered termination, and said that sadly my experience was not unusual.
Incidentally, two obstetricians have told me that, according to the research evidence, around 10% of babies with talipes also have serious genetic/chromosomal abnormalities. However, the quality of that evidence is not great and it is mostly very old and up to date. One said to me, "I don't dispute the evidence, but I have to tell you that it doesn't tie in with my daily experience, which is that children with talipes don't have additional problems at anywhere near that level". He also said, "There's no guarantees, but honestly I think you should just get on and enjoy this pregnancy".
Sorry to ramble on: what I'm trying to say is that (1) IME how talipes gets diagnosed and discussed during pregnancy can fall very far short of ideal, and (b) I think my obstetrician's advice applies to you, too.
