Hi my 10 yo girl is short by age. And I am worry this will eventually affect her self esteem. What can I do?

I think there's nothing wrong with being short! It doesn't really matter, but what you could help with is probably to guide her when she feels that way :) Throughout my childhood (even until now), my parents have always been the ones making snide remarks at how ugly or fat I was - it doesn't help when my peers were doing the same at school and it caused a big scar because I didn't get the support I thought I had from my parents. She probably hasn't been through the full puberty yet, so don't worry too much about it!
