I really feel you on this, as a first-time mum it is so hard to know what is the "right" way, and honestly there is no one answer that works for every family. My girl slept in our room for the first few months and when we moved her to her own room around 7 months, there was definitely an adjustment week or so, but she settled faster than I expected. do not stress too much about which way you start, you can always adjust as you go and follow what feels right for your family at that point.
