My four year old is finding it really hard to make friends at school. Apart from one very kind little boy the other little girls are excluding her and making her sad. I have tried asking other mums via the WhatsApp group for playdates, and explained the situation but it's heartbreaking to see her so sad. She's a good, caring little girl, not rowdy or spitefulat all, but I dont know how to help her. Any suggestions woukd be welcome.
