I always bf mine in bed with me at night.I'd drop off every time.I left the telly on,the light on,anything,but I'd drop off they'd go to sleep feeding,but I always put them back in the cot as soon as I knew they were properly asleep.I still drop off feeding Merlin,and he's bottle fed,but same again,he goes straight in the cot.I don't want my babies to be dependent on me to get to sleep.I wrapped them and gave them a raggy from birth,and they use these as sleep aids,not me.All of them have always been happy and secure,and go straight into their beds.
I don't think there is much advice given on settling babies and establishing good sleep habits.
Cot death is the unexplained death of a baby,so any study that finds any cause or link to anything we could do to prevent it,maybe cases can be reduced further.
