When to move baby to crib

Rey

When did you move your baby to a crib in their own room? My first got moved at 3 weeks old much to my paranoia because she simply could not sleep with my husband snoring. My second is 2 weeks old and seems to have no issue sleeping through his snores but my now almost 3 year old is having mega jealousy that baby gets to sleep in our room and she can't. I was thinking 3 months but conflicted because of reading recommendations of 6-12 months whule also trying to get the transition done before the separation anxiety heightens but after the transition of me going back to work and daughter going back to pre-k. Would love to hear thoughts on what worked best for everyone!
