Will my next baby have trisomy 18?

Another one of those top 10 questions. Your baby has or had T18, you are fortunately pregnant again and you want to know what is the chance is that this new baby will have T18 or even another trisomy.

This is isn't a clear cut question. First of all it depends on what type of T18 your baby has/had. If it was partial T18, you and your partner should have been tested to see if you passed it on and if you did, you should have been counselled regarding the risk of T18 to future children. If your child had PT18 and you haven't been offered this, then ask for a referral to genetic counselling.
