Taina did the same thing at five months, it took A LOT of willpower not to take her out but you already know if you do it once she'll keep thinking she can do it. I would just invest in some earplugs until she knows she's not to be let out until YOU get up. Take her out though after 6 hours of sleeping, at 5 months she may not be able to hold it for a whole 8 hours. But once she goes put her back in or contain her somewhere while you sleep. I'm not an expert but it helped with Taina. Good luck!
