We plan to do our newborn photos at 4 weeks so we have time for unbilical cord to fall off and I can deflate a bit:) But now that I am shopping for his stuff, I don't know whether to get NB, 0-3, or 3M stuff? (some stuff skips 0-3 and is just nb or 3m).

Ordering after baby is born isn't reeeeeally an option only because I don't want to worry about it coming in on time or me simply forgetting.
