At 19 months I reckon this is "age appropriate behaviour". I don't think it's anywhere too late to start teaching this kid to be respectful to others - and that's always something that you do by being respectful to the kid.

Somewhere along the line this kid is frustrated by intrusions into his own boundaries and it leads him to not respect other's boundaries. The more aware he becomes of the feelings of others, and, more importantly, aware that other's feelings COUNT, the more gentle he will become.

The more compassion your grandson sees, the more he'll be able to exhibit.
