So, DD sleeps in a PnP right next to the bed.  For her MOTN feeding(1-2am), I bring her to the big bed and sidelay.  We usually fall asleep and eventually I wake up and move her back to the PnP.  
Lately, DD doesn't want to go back to her PnP. She fusses when I try to return her and then wants to eat a little more (seems more like comfort nursing than I-am-hungry nursing).
I wake up she is cuddling my boob like she cuddles her lovey!
I am worried that she is getting too used to bed-sharing. But I secretly love the baby cuddles.
Did I spoil her? 
Re: I may have created a monster...
ha! I have been worried about this with my DD too. for me its not the motn, its first thing in the morning I have been bed sharing and side laying nursing. Now she seems to only want to lay in bed and nurse 24 -7 (which makes it hard to get ready and leave for work), and she is cuddling the breast in sheer delight.
IF you spoiled yours, I have also spoiled mine ~ we should form a club.
DS has started to do this too. He starts the night in his bed, but after he eats in the MOTN, he won't go back to sleep unless he's laying right next to me. I even tried moving away from him last night, and he whined until I moved back so his face was practically smushed into my boob.
I wonder if maybe it's just the age.
