I see you are in Canada... the recommendation here is 6 months minimum in your room. Honestly your friends are probably making more work for themselves! Some babies are calm enough to not demand constant night wakings but why make more work for yourself? You're already tired and exhausted from labour. My newborn doesn't even cry at night (except diapers) because I wake up when he stirs.
Remember that crying is a LATE sign of hunger in babies. When you have to get up and go to their room (or make a bottle before that) because you hear crying, the baby is already frantic with hunger and if you are breastfeeding, makes it hard for them to latch (and bottle babies may take in a lot of air and get painful gas by that point). Rooting and sucking their hands is an EARLY sign of hunger and if you feed them before they start crying, they will feed easier, take less gas, and go back to sleep quicker. You can't know this from another room - but you will sense this if you are right beside them.
So, from a biological standpoint, it makes no sense for anyone really to put the newborn in another room. Some choose to do so (and I've done it with my 1st) but for most, it makes more work and stress.
Besides, whatever your friends are saying, your instinct tells you otherwise. You have those instincts for a reason remember!
