My baby is 13 mos old and we always do story time and then I nurse him, sometimes sing, and he falls to sleep. He has always slept with us in the family bed. I would go with what you feel is right. My doctor in the US was a very progressive guy--he never recommended sleep training. It can sometimes take a long time for him to fall asleep, but I know most people say that they learn to do it on their own eventually. Don't go by weight charts too much, if you are nursing your baby, it is probably the right weight.
