J.P.
I to have two daughters that are five years apart. For about the first 6 or 7 months my youngest sleeped at night next to my bed. I had a crib in my oldest room and that is where my youngest would take naps. I breastfed so it was just easier for her to be next to my bed at night, but as she got older and sleep though the night more I moved her into the bedroom with her sister. My mom had a fit because she thought that is was not far for my oldest to not have her own room, but my oldest did not mind and wanted her little sister to sleep in her room. They are now 7 and 2 and still share a room. We moved into a bigger place about a year ago and since they share a room they got the biggest room in the house. It makes it so much easier to keep there stuff organized and they like having someone there when they sleep at night. Hope that helps good luck.
