I know the boppy says to not let baby sleep in it but she will not sleep in anything else. Baby girl will fall asleep no problem but whenever I go to lay her down in her crib, pack and ppla or swing she wakes up either before I lay her down or barely even 5 minutes after I set her down. She used to sleep in her crib without a problem but now she would rather sleep in  daddy or I's arms.  
Out of curiosity I laid her in the boppy for her nap and she is sleeping like a champ. I don't leave her side when she is sleeping in the boppy but I'm wondering if any other moms have done this and what their outcome was.  Baby will be three weeks tomorrow..                
                             
        
Re: Boppy sleeping
my daughter loves her Boppy lounger too. She takes most of her naps in it. Only thing is that you still have to supervise babies in the lounger.
You could try having someone else put LO in the crib. DH has much better luck than I do! Or you could snuggle LO in their swaddle so it's still warm from you.
