If my SO mom tells me what I need to do & dont need to do with my son one more time I will lose my religion. She told me I dont need to get a bed for him that he will be fine in a pack & play because he is to small for a bed. We got into it all because I wanted to clean & organize the room so I can make room for him. Dirty ass had everything molded in that back closet so it all had to be thrown away & I bleached & scrubbed the hell out that closet. She thinks shes parent of the year, but shes about as shitty as they come.
