Sorry in advance for the long post. But i am sick of mothers being made to feel like bad parents for co-sleeping when i believe it can be so beneficial.
I agree that you should check re. prem babies.
I had exactly this with my DS (the wind and discomfort) and the only way he could be comfortable was lying on his tummy. I didn't want to put him down in his moses basket on his tummy, but felt comfortable sleeping with him on my chest. I used to push the duvet down and cover us with a single blanket instead. I won't lie, i used to worry about SIDS initiallyt primarily because co-sleeping isn't 'the done thing' in the UK based on the advice. But when i looked into it further i stopped worrying. Even my health visitor said "whatever you need to do to get him through this period with your sanity intact, do it - trust your instinct even if that means co-sleeping".
Here are a few things about co-sleeping and SIDS that are not well publicised:
Co-sleeping SIDS deaths in the UK are mostly extremely tired parents falling asleep on the sofa with their baby. The incidence of SIDS deaths in parents beds are actually very few - around 1% i think (there are around 300 SIDS deaths in the UK each year). Clearly if you and your baby are getting a reasonably good night's sleep in bed together then you won't be overtired in the first place.
Co-sleeping is more risky if you or your partner drink, take drugs or smoke.
Co-sleeping is accepted, and encouraged, in many cultures. In co-sleeping cultures where drug taking/ alcohol consumption is more prevalent SIDS rate is quite high. In cultures where drug taking and alcohol consumption is low, SIDS rate is low. Spot the common theme?
Do it safely, use your common sense and it will be fine i'm sure. And don't go down the 'risking his life' route. You're a great mum for worrying in the first place. My DH has let my DS slip under the water in the bath twice now. Apart from a bit of coughing and spluttering he was fine. No harm done.
Ditch the duvet and take up the blanket (or a grobag when he's big enough and put him on top of the duvet). Push the pillows well out of the way and always make sure your partner knows he's in the bed. And keep trying to settle him in his basket at his last feed just in case one night he's improved enough to tolerate it.
