My daughter is just over 10 months old and I've been thinking of starting the weaning process. So I thought about substituting a feeding once a day for whole milk instead of breastmilk. I've been hearing mixed thoughts about what age is safe to do so. Some people have given their babies whole milk at 9 months old (even said their doctors recommended it) and others say you MUST wait until they're at least a year old. Do you have any thoughts on this?
