Hi Sarah, Wishing you all the best.

At my 20 week ultrasound we found out our bubs has a cleft lip +/- palate so I know how you feel. No matter how little the problem is (compared to what can happen) we still feel devastated. Anyway as with you everything else looked fine but since it can be associated with other conditions we went on and had an amnio just to be sure which fortunately was all ok.

A club foot is the most common abnormality that a baby can be born with and generally is isolated and managed well with plastering +/- surgery. I'm sure, as in our case, they are doing the repeat scan + amnio if necessary just to be certain everything else is ok. Also, as was mentioned Trisomy 18 is not generally something that can be passed on like some other genetic conditions so I wouldn't worry about that.

Good luck with everything. I'm sure it will all go well.
