When my DGD was 15 she moved in with us, said she had had enough of her parents! She stayed for a couple of weeks and then happily went back home. She is 16 now and turns up after school now and again. She stays for dinner and we treasure the time she gives us. Her 8 year old brother comes daily to us during his holidays, and every so often he packs a bag and tells us that he "may as well stay the night - no point going home as he is coming back the next day anyway" ! As someone who didn't have grandparents, I am really grateful that I can give my GC this experience, and as fo DH and me - well we are in Paradise! So enjoy and allow them to create memories that will help make them into wellbalanced adults.Spoil away, it is your duty!
