Sleep

So I’m pregnant with my second, he will be born before my other little one turns one. Me and my partner currently sleep in one room with my first baby. She sleeps in her own crib. But Im debating if I should have my new baby sleep in the same room as us or if me and baby should sleep somewhere else until we regulate a good sleeping schedule. My LO is a light sleeper and I don’t want her to be up at night and fussy during the day. Should I just have everyone sleep in the same room so she gets used to the noise/crying? Or wait a few months? Any recommendations?
