For our first baby, we were told by various midwives in no uncertain terms, that babies must always be placed on their backs to sleep (no explanation ever given- just instructions!). This was all very well, but our little boy just wouldn't stay asleep for more than a few minutes on his back before waking himself up crying.
It was only when his Grandmother came to stay after a few weeks and placed him on his front that he actually had any kind of lengthy sleep at all. She says that the advice used to be to always do the exact opposite, and place babies on their front to sleep.
We are now expecting a second child, and would like advice as to whether we should try our best again to place him on his back as before.
