Oh dear lord.
3 yr old DD with autism 'motorboats' people, according to that description.
We're trying to teach her not to, & about boundaries & personal space, but she really really loves boobies & struggles to supress the urge to nuzzle them.
Not just mine, Paeds, Doctors, Nurses, MPs, Teachers, Neighbours.
If you have a cleavage then DD is going to want to snuggle up & blow raspberries on it. Perhaps I shouldn't have weaned her quite so early.
