I'm so worried about my little Granddaughter who has just turned 6. She plays up every morning not wanting to go to school and continuously says she hungry. There is no problem at the school and when my daughter does her food she won't eat it! We're at our wits end not knowing where to turn. She is very petit and we're concerned she isn't putting on any weight! We have tried everything. Any suggestions would be so gratefully received. Thank you.
