we had a scarey incident on the week-end where I woke to hear DD (6.5 months) choking in her cot as she had vomited......we had to get the ambulance and take her to hospital to make sure non had got in her lungs.
BUT, since then I can't get her to sleep in her cot without lots of crying, feeding or rocking her to sleep with music playing. I think she now has a bad association with the cot.
We used to be able to put her down at night after dinner and bath and she would happily "talk" to herself and blow raspberries etc until she fell asleep, but now she seems distressed, cries, arches her back etc....making me very distressed!!
