I'm seeing different takes on whether toddlers can actually be "spoiled", and I'm wondering what your takes are on this.

On one hand, I read that all toddler behavior is normal and it's normal boundary-testing. My 19-month old son doesn't want to walk (though he can) and will throw tantrums if he's not carried around sufficiently. I will say "no", but the tantrums persist. He doesn't do this at daycare. However sometimes he loses points for his "comprehension of limits" rating. Do you think toddlers can be spoiled and if so, what are the tell-tale signs?
