DS is getting to an age where he can play at a playground with other children and I don't know what the etiquette is in the situation I experienced today for the first time.
Another toddler kept pushing DS and shouted at him to get out of the way whenever he went past. DS didn't respond and I couldn't see the parents of the toddler nearby. When the toddler pushed my son for the fourth time I looked at him sternly and said "no! We don't do that!" Toddler threw himself on the ground and had a tantrum but then got up and carried on playing, and didn't push my son again.
Was I unreasonable to "discipline" the other child? I wouldn't have liked it if someone else had done it to my child but then I would hope I stay nearby and keep an eye on him so I can step in.
