I am a single mother and my daughter is missing her father as she sees fathers coming to pick up their kids at school.now she can be seen irritated and sad any suggestions

A. See with growing age kids do miss a parent of the parent is not around so whatever your situation has been that it’s a separation or whatever your personal situation is that you are a single mother you have to explain everything to the child from an early age itself to know the child that what has happened why you are a single mother and other situations as you have not mentioned that are you separated or divorced or anything so better to explain it to the child clearly
