I cannot agree more.
It really irritates me that older generations (above 40s) tend to hug and kiss my 15 months baby whenever she wants to. I always warn them (in a friendly manner) that kids should not be forced to do that as it can affect their emotional development.
Lessons about consent begin at a very young age. If we want our children to respect other peoples' bodies (and demand respect for their own bodies), we shouldn't be sending mixed messages by letting people hug and kiss and touch them against their will when they are babies!
