I’m going to buy my SO his own bed

So we cosleep with our daughter. She’s against the wall , I’m in the middle , and he’s next to me. We have a king sized bed so it’s pretty spacious. We all have our own pillow and fit perfectly. But I swear he is ALWAYS somehow a little on my pillow. And I can just feel his body physically next to me, I like to like spread one of my legs at night so it pisses me off when he’s on my side lol. I literally just put my hair on him and he moved 😂😂 our daughter is going to have her own little bed soon so hopefully this will be over
