Hospital visits

mommies I'm having my daughter in May, I wanted to know if in Texas I can prohibit anyone from entering the room to meet my daughter? I misscaried the month before i got pregnant with my daughter due to stress and all the emotions from my grandfather's passing. About 2 weeks after that things with my in laws went down hill, I'm ok with my husbands parents but his sister is just so childish and gets mad over anything making a big deal and I'm just tired of dealing with it plus her husband does drugs and I dont want that around my kids and my husband who is attending rehab, I don't want her to visit us at the hospital my husband agreed that if there was anyway to prohibit her and her husband from visiting to go for it. Does anyone know if there's anything I can do?
