AITA for moving our baby three rooms away from our toddler?

My 5 year old daughter is generally a very confident, outgoing happy little girl. We're a 2 income household, so she's been in daycare since she was 18 months old, and she's very outgoing and does fine. My husband and I are thinking of trying for a second kid in the next few years, and our daughter has been begging for a baby sister so she can have a "best friend forever" (her words). We were on the fence since having her was a difficult pregnancy and I'm not sure I can go through that again, but after she asked us so many times, we decided to just go for it. Well, we found out I was pregnant with our second child in the spring, and she was over the moon.<br><br>Our LL is currently our nursery. My daughter used to sleep in there when she was a baby. Our bedroom is just across the hall from it. <br><br>When we told her that the baby was coming, she immediately said "Oh good! Now my best friend forever can have a place to sleep when she gets big enough! I get to sleep in the big girl room now!"<br><br>I asked her what she meant by the "big girl room". There's a big bedroom right next to ours, and she said she meant that one. When we moved into our house, we thought that might be a good room for our daughter, but she was afraid to sleep that far from us. She always said she wanted to be close to Mommy and Daddy. So at the time we decided it was no big deal since she was only 2, and we could change it later.<br><br>My husband and I talked about it, and thought it was perfect. The big girl room is big, my daughter was happy with the arrangement because the big girl bedroom was next to our bedroom and she could be "close to Mommy and Daddy", and it made it easier for us to have the baby in the nursery.<br><br>When our baby was born, my daughter was so excited. And our baby is a girl. My daughter loves her so much, it's so sweet. She's been begging for us to wake her up in the night when the baby needs to be fed so she can watch or help. We told her no because she needs her sleep for school, and she needs to be well rested to help during the day, but she could definitely see the baby after feedings and spend time with her in the mornings before school. <br><br>The first night we brought the baby home was hard. She had colic and was crying a lot. My daughter had trouble sleeping because the baby was so loud, so we moved her to the big girl room for the night and told her she could come back to her old room if she wanted to in the morning. She said yes, but the next morning she said she wanted to stay in the big girl room so she could still be close to Mommy and Daddy but also get a good night's sleep so she could play with baby sis. <br><br>Now I get multiple texts a day from my husband that my daughter is coming to him at work, asking if baby sis is okay because she can't hear her crying anymore. He says no, she's fine, and my daughter just keeps asking. She's also started spelling out words she doesn't want baby sis to hear because she thinks the baby can hear her from across the hall. It's kind of adorable.<br><br>Anyway, I just wanted to share this story because it's something I never would have expected and I can't believe how far the tables have turned.
