DD is 6 and stays at her dads place with him and his gf every other weekend fri-sun. They both smoke but I've asked them not to smoke inside even when dd is not there because of the chemicals etc. They have agreed to this but some of the clothes she brought home a few weeks ago smelt if stale smoke. He said this was because he'd left them in the car and he'd been smoking in the car (something else I'm not happy about). Today, more clothes have come home smelling of smoke. They are obviously still smoking indoors. Is there anything I can do?
