Thanks so much for the answers, and thanks @JandL2020 for inquiring, that is so very kind of you. @whatsgoingon22, I had 3 consecutive losses at 8 weeks (subchorionic hematoma), at 7 weeks (blighted ovum), and a late second term loss (because of failing placenta). I then had our DC out of out fourth pregnancy, who was born more than 2 months prematurely, again due to a failing placenta, despite being on aspirin, clexane, progesterone, etc.
I would love to have a sibling for baby (there are not a lot of potential playmates around here, and I had always hoped for a bigger family). However, not if we cannot guarantee a smoother pregnancy. We spent weeks and weeks in NICU with baby, and it was very stressful. Although delayed in some areas, baby is now on track in others, but we have been so concerned about baby's development after the prematurity and low birth weight. It was impossible to relax and enjoy and we had many medical appointments in their first year of life.
I don't think it is ethical to put another baby (or us and our families) knowingly through that type of stress again, or leave my current child neglected for months at the time, while I am spending all my time in NICU with a sibling. Moreover, such early prematurity comes with such risks to the baby's health and wellbeing, that it feels like playing Russian roulette. So I am very much looking for answers that might give us a chance at a better pregnancy. I am also 40, so time is running out.
If we can't find a solution, we will thank our lucky stars for the one child we have been able to have - I do realise this is a huge privilege already, and don't take it for granted.
I am wishing you all so much good luck. I definitely have been there in the non-stop testing, timed baby-making, nerve-racking scans, foetal medicine appointments, etc. I have also been there with the 'why us?' questions. So sending loads of good vibes all your way.
