HELP!!! We Have No Control What So Ever with Our Child GRRRR!!?

my husband and i have been staying with my parents since we had our first bby girl which happend to be the first grandchild as well. Since the day she arrived while we work n finish our college years my parents offerd to bby sit. Well when we say No to somethiing they just give it to her anyway they take her wher they please and tell us our car isnt full coverage so we cant take her when ther vehicle is only liability as well. She even sleeps with them in the room every single night and when i try to take control and say shes sleeping with us she'll cry and my dad will throw it in my face saying " I TOLD YOU SO" i understand the caring and the loving but i mean when i say no candy i really mean no candy but do we get heard NO! We still get trated like children and we dnt knw what wer doing. * sigh * physiologically the mother and child are to have thee strongest bond yet we get treated like wer my daughters older bro & sis. We want to move out to build a mother & father relationship with our daughter but it would be ripping her frm my parents! WHAT DO I DO SOMEONE PLEASE!!!
