son (6) has made a list of things the baby is not allowed to touch

his room is on it. so is a blanket he hasn't used in two years. and his cycle, which the baby will not be riding for some time 😄 baby comes in Feb, will sleep in our room at first. but at some point they'll share and he knows it. don't want to promise him nothing will change because that's not true. how did you talk about sharing without making it sound like he's losing stuff
