I am also in the "you can't spoil a baby under 1 year" camp.
My midwives told me, the amount that you want to hold your baby, is how much you should hold your baby. If you are fine putting baby in a crib to nap (and baby is ok with it) then do it, but if you want to hold her, hold her.
That was a relief for me, because I wanted to hold DD all the time, but I felt like I shouldn't and I would be spoiling her. But once I got the go ahead, I held her a lot and my now 9 month old is not spoiled at all.
