I think often the purpose of these classes is to educate grandparents about practices that have changed since they had children. For example, it used to be very common for parents to be advised to put babies to sleep on their stomach, for fear of them aspirating if they vomited or spit up. We now know that this increases the risk of SIDS/cot death, and it's much safer for babies to be put to sleep on their back.
Yes, but so much was written in news about the changed sleeping position and why and is so common in the main news media these days that anyone who doesn't already know that probably doesn't want to.
Grandparents faall into two groups, the sensible ones who listen to the childs parents and do as they wish and the awkward and difficult ones who always know right. One does not need lessons, the other ones would just argue with the tutor.
