Basic risks: You have taken common steps to improve your outcome & this helps. There is a baseline of about 4% of risk that some issue (cleft, chromosome problem, premi, etc. ) can occur in any pregnancy.Most cases of arthrogryposis are due to a sporadic muscle problem with minimal recurrence risk. It would help to sit down with a geneticist ( @ children's hospitals) and review your specific risks.
