when to let your baby stay the night somewhere

britney
My family member is insistent that my baby needs to stay the night at their house so I can get a break. I keep telling them that it's fine and that it would be more trouble than it's worth since I am EBF. Even if she stayed at their house I would still have to get up in the middle of the night and pump since she wakes multiple times a night to feed. And I would have to pump enough for her to stay there-which is a lot of work. It's not like we don't see them often. We go to their house usually once during the week then every single Sunday for dinner. My baby doesn't like being at their house past eight o'clock. I think it's because it's extremely loud and chaotic. They've got four kids who are preteens and teenagers who always have someone over. At any given time there's like 12 people there. She screams until we get home. She just likes being at home for bedtime. They keep telling me I need to break that habit. But I don't understand why-I enjoy being at home for bedtime why shouldn't she? 
  
They also keep telling me how I need to give her cereal to help her sleep because they gave it to their babies at a month old and rhey always slept through the night. I've told them no my pediatrician doesn't recommend it and I don't see a need for cereal. Plus she's breastfed. I'm not going to pump a bottle when I could just feed her. So I feel like they just want to keep her so they can try the cereal and see if it helps her.  
  
I've also told them I'm not ready for her to stay somewhere. She's only twelve weeks old. I'm running out of excuses and my patience is wearing thin. Am I being too much of a helicopter parent? When did everyone else let their babies stay the night with family members?
