Visitors

Our baby is 2 1/2 months old and my husband's cousin and his family want to come visit tonight. I'm totally ok with visitors but they want to come over at 8:30 tonight. I've been working hard the past couple of weeks to start a schedule with our baby and she usually goes down at 7:30-8:00 for bed. We have a bedtime routine prior that we do to get her ready for sleep as well. I'm annoyed that he wants to come with his wife and 3 kids so late, am I being too uptight about this? I usually head to bed around 9:00 because I'm up a few times in the night with our babe. Please tell me if I'm normal or not normal for feeling this way!
