Co-sleeping

I live with my boyfriend of two years. He has 3 kids, 14, 11 and 7, that stay with us every other weekend. Every night they're here, around 6 in the morning, the 7 year old crawls into bed with us. It makes me feel really uncomfortable. He also kicks and lays over the covers leaving me with none. I don't know how to bring this up to my boyfriend. I understand he doesn't see his children all the time and I don't want to be inconsiderate but I feel like our bed is our bed. It's an intimate place and I believe the child is a bit too old to be crawling in bed with us anyway. I know it's a touchy subject. Any advice? via /r/Parenting http://ift.tt/2y1lKBk
