Mackenzie was feed or rocked to sleep up until she was about 12 months old. I don't think created any problems. We did try controlled crying a few times but it just stressed us all out so abandoned that one fairly quickly. She is now 2.5 years old, sleeps in a bed and stays there most nights no problem. We do have the odd night where she feels shes had enough sleep and jumps out of bed (ususally within half an hour of going to bed) but we just put her back in and shes fine. She still wakes thru the night, sometimes I have to jump into bed with her but other nights she just needs a rub on the back and she goes back to sleep. Every child is different and the best advice i got was from my mum who told me you can't spoil them and they are so little for such a short time just enjoy the cuddles. It's up to you to do what you feel comfortable with and if its feeding and rocking to sleep so be it.
