Social child 👶🏻

My daughter is very social and friendly but sometimes other kids don’t respond nor the parents…. How do you handle these situations to not discourage ur child from being social? I know other kids r shy or more reserved but as a mom it kinda stings to see the child kinda look afraid of my daughter saying hi from a distance and even more so when I see the parent completely ignore. Idk what’s appropriate what’s not have you been in similar situations from either side social kid or more reserved. I’d like to hear more POV
