Did you actively encourage your child to only feed at certain times, or did your child cut down on feeds by him/herself?
When my dd's were coming up for two I started to introduce certain rules when they could feed - and they were quite happy to go along with that. This led to my dd1 gradually self-weaning, my dd2 cutting down to just one feed a day.
In that infamous programme today on Ch. 4 it struck me that the women all seemed to allow their children to feed whenever they wanted - and I wonder if this is typical or more my experience?
