Thanks again everyone- especially EvilTwins- I'm scared enough without scaremongering!
I'm going to be controversial here. (Probably not a good idea.) But throughout my pregnancy I've been struck by the amount of scaremongering that goes on with regard to so many aspects of pregnancy: everything from eating pate and cheese, to the odd glass of wine, coffee and electric blankets, through to the truly bonkers (stress will make my baby gay, will it, Sunday Times? Wearing makeup could harm my baby, could it, Royal College of Obstetricians?). I was very grateful for Emily Oster (Expecting Better) for taking on some of the most common warnings and using her analytical training to prove that there was only limited basis for many of the warnings women received while pregnant. The fact is that most of the time we don't know what causes the awful experience that is miscarriage, and our natural instinct is to find something to blame.(I've had a miscarriage, so know what it's like to look for answers and find none.) Or to find something the mother has done, and blame that. Hence the endless speculative articles and over-cautious advice.
From everything I've read, nobody knows what causes SIDS. So like miscarriage, there seem to be many, many things that the "experts" say you must or can't do, but no absolute proof of what causes it. Babies have (tragically) died of SIDS while in the same room as their parents, and while in separate rooms from their parents. And the difference in rates between the two situations is not enormous. If we could prove that very few babies died of SIDS while sleeping in their parents' rooms, and that the vast majority did while sleeping in separate rooms, that would be proof. That's not the case. So perhaps there's another cause.
From the website I was given upthread (and much other advice) it seems that it is unsafe to leave your baby alone at all while it is sleeping. Isn't this overly cautious? Doesn't every parent put his/her baby to bed at 7 pm and go to bed hours later? Does every parent have to go to bed beside the baby for every nap?
I hope that this won't cause too much outrage- and apologise in advance for upsetting anyone. But throughout my whole pregnancy I've been hearing the "but would you forgive yourself if anything happened?" line, and it drives me crazy, because it's just lazy. I've read huge amounts of data/research on what is and isn't recommended in pregnancy and I've been able to make up my mind based on facts. (The odd serving of liver pate, for example, is No Harm At All unless you're stuffing your face with it all the time and/or taking Vitamin A supplements. And don't get me STARTED on the coffee hysteria that's based on a flawed study...)
So I just want to know WHY is it dangerous to put my babies in a separate room? When by extension of this logic NO baby should EVER be left to sleep in a room without an adult in it? (and people do this all the time...) When by extension of this logic NO baby should EVER have died of SIDS while in a room where an adult WAS sleeping? (and this happens in at least 40 per cent of SIDS cases...)
It's all starting to sound depressingly like the finger-wagging pregnancy "advice". Medical community can't explain something so gives out up a load of rules which everyone has to follow- which still don't really go any way towards eliminating SIDS. (Apart from the "back to sleep" advice which does seem to have made SIDS rates drop significantly.)
I realise now that this has turned into a rant, and of course nobody here will be able to give me the answers. But I think I needed the rant. I'm still blaming the hormones...
