Soldato
TBH, they're not usually much cheaper and the lenses are more expensive and there's less choice.Get a mirrorless camera!
Compact, cheaper than an SLR. SLR quality photos, lightweight, easy to carry around for baby shots.

But I would probably also recommend it anyway, I like the NEX's, get a fast prime to go with it and you can take all kinds of DOF laden baby shots.
