Is it true that you can't spoil a baby by holding him/her?

I remember reading somewhere that you can't spoil a baby by holding him/her too much, that this was a very old myth. It seems that my month old newborn only sleep soundly while I'm holding him or he's lying next to me in bed. Is this normal, natural or having I been cuddling him to much already? Right now its fine, I just don't want to have to hold him/sleep with him all the time to keep him asleep in the future.
