Hi hsmom I just saw this thread and wanted to add my story to the other encouraging ones as I know how good it is to hear them when you are going through it!
My 12wk scan with DS2 was perfectly normal, but at 20 weeks only his head measurement (barely) made it on to the chart, he seemed to be about 3 weeks behind. Dopplers were normal except for the reverse flow, which was absent, the significance of which no one seemed to be sure of at any time.
We were told the most likely explanation (by Prof Nicolaides team at Harris at KCH) was severe, early onset IUGR and the outlook was poor. His estimated weight was 120g and as you know, the target for delivery into scbu with a good outcome is 28wks and 600g....which seemed such a long way away. We had amnio, TORCH screens, achondroplasia tests done, all came back clear so we then continued to scan every two weeks (and torture ourselves with what awful conditions might be causing the growth restriction-please try not to do that too!). Like your little one, DS2 also seemed to defy expectations because he continued to grow at normal velocity, following a standard curve but right at the bottom, or below the chart. The prof suggested that maybe there had been some damage to placenta early on but that it had repaired itself..some amazing things can happen.
We made it to 37 weeks, at which point the fluid was low, so they induced me. DS was born weighing 4lbs but fine, no need for scbu, just 3 nights in hospital to
get his blood sugars up and treat a bit of jaundice with
light blanket. He is still, at 13m and approx 7kg just below the 0.4th centile but perfectly normal, developmentally on track (chatty, says mama, dada, sibling names, feeding himself, almost walking). He is the happiest baby I have ever met and so cute. Although we hope he will catch up in size, after such a stressful and seemingly never ending pregnancy we feel so lucky to have him. I really hope you have a similar story to tell soon, it sounds as if it may be heading that way
. keep us posted, I will be thinking of you and wishing you well.
