Hi Loopy - I don't really know where to start except to tell you my story. We did exactly the same as you but were given a 1 in 5 risk of DS. We didn't have invasive testing for the same reasons as you and a cardiac defect (AVSD) was picked up at the 20 week scanfter that scan, the medics said they were 95% sure that he had DS.
I know it is different for everyone and you may have read some of my threads already but I gave birth to a gorgeous boy 12 days ago and we have all fallen completely in love with him!
Anyway - coming up to the birth I suddenly got cold feet about how I could possibly cope and was actually quietly terrified about meeting him for the first time - not really knowing what to expect. My waters broke and my body started shaking uncontrollably as I was so scared about what was to come (not the labour, just meeting the little fella and how I would feel). I ended up having to be induced 2 days later because labour didn't start naturally.
He was born after a 1.5 hour easy labour and I turned round to see him and knew instantly that he had Down Syndrome - I just scooped him up saying 'oh you do have down syndrome' and asked the midwife to cut the cord asap.
The consultant had come in to see us while we were waiting for the induction to take effect and asked what we were planning to do with respect to cutting the cord. I said that I wanted to wait until the cord had stopped pulsating and he said that if baby did have DS, then it would be wise to cut the cord asap because most of them are born with polycythaenia ('sticky') blood and allowing more blood to be pumped in to them by the pulsating cord can exacerbate the problem and that if this was the case, he would need blood taken away and saline added to dilute his blood down. This made perfect sense so we agreed to have the cord cut straight away. He also said that it might not be obvious whether or not he had Down Syndrome though usually they can tell but that they would send off a blood sample for full karyotyping and results can take about 5 days.
We had a big cuddle and then consultant came in and examined him and then said that he thought that baby did have Down Syndrome and that he wanted to take him in to the neonatal unit (room next door) to check him out properly and do an echo to check his heart and scan his head too etc. So, quite quickly, I had a shower and we all walked round to neonatal unit and they checked him out. They did end up having to do the dilution on him anyway. He thought he found something extra going on with his heart and transferred us to another hospital but it all turned out to be fine. He also had some jaundice so had phototherapy for a night but everyone was fantastic and made sure we had all the info we wanted and answered any questions that we had etc. Not once did we feel scared, worried, anxious or out of our depth. It was all very calm and relaxed.
Anyway - he took a bit longer to get breast feeding going becuase he was so sleepy! SO sleepy!!! But perservere I have and all is good and he's gaining weight etc. We have had a couple more appointments since just for routine checks to do with his heart defect plus another because he has Down syndrome but it's all very low key.
DH and I were saying today that apart from day 1 when we really noticed his DS features, we just don't see them any more and neither or us were expecting that! He really does seem just like any other baby and he;'s totally won us over!!
