As BG said, Samuel was a SUA baby... I just didn't see this thread until now!

As mentioned, SUA can be an indicator of chromosomal abnormalities, kidney defects and heart problems. Most of the time, these will have been ruled out at routine 12 week scans (chromosomal problems) and the 20 week scan for the kidneys. They will usually do further scans in pregnancy to monitor growth and heart problems. Of course, they don't tell you that most of these problems will have already been ruled out and you'll come home and google and freak yourself out in a huge way...

SUA can also lead to low birth weights and early arrivals.

For those who are hearing predictions of monster-sized babies... At 18 weeks when our SUA was diagnosed they were predicting a tiny baby. At 24 weeks we'd caught up and were right on average. At 32 weeks they started talking monster baby... At 36 weeks I gave birth to Samuel and found myself with a 2.48kg tiny baby in SCN for 10 days! Take all the predictions with a grain of salt.

As for the early arrival thing - I have a friend who also had a boy with a SUA - he was also born at 36 weeks.

The only issues after birth relating to the SUA that we've found is that we were sent for a routine kidney scan just to double check that there are no problems. The paed didn't expect to find anything, but it's just something they do, apparently.

I hope this is helpful - just remember that just because it can mean something doesn't mean it will.
