My oldest, went through a phase of wanting to sleep in my bed. Let's say, he's a bed hog, those times I entertained it, were the worst nights of sleep for me, and let's discount the couple of 'accidents' all over my new mattress.
And what about, my own insomnia, waking up, and not being able to go online, turn on a light and read, and certainly, no way, for me, to take a sleeping pill, if he's in my bed.
I have three sons. is it fair, to the other two, if he did this? Am I soothing him, or me? Then, at what point, was there struggle to break, what becomes a habit??

Four, five, six, seven, eight...when does it become, a bit excessive? My son, through those ages, went through this. And, it turned into, a putting foot down. It wasn't continuous, through those years, but tears were shed, they needed to be shed.

Good Luck, having this talk with your gf. It's a hot button topic.
