if you feel comfy B/F back to sleep and it only takes 5 minutes to do so, then i reckon go for it. i spent WEEKS feeling bad that i was doing something that i would later regret; but it didnt happen, DD went back to her good sleeping pattern and hasnt looked back.

i too found that there were certain 'stages' where sleep became more confused...first at 8-9 weeks, 6 months and 9 months. this could just of been our DD, but i think there is a ring to it as it seemed to correspond with something going on with developmentally (ie it all went to the rocks when she was learning to sit, crawl or walk). then she would achieve her milestone and go back to being a strong sleeper...

i hope that makes sense LOL!!
