On a normal basis, I discourage matching furnishings, but for nurseries it seems very appropriate. It gives a crisper, cleaner look, which most new moms find to be very appealing in the "nesting" period. If a whole suite of furnishings is purchased you should have a crib, changing table, and chest of drawers or armoire. White painted, natural or stained woods are my general recommendation. I don't believe in purchasing new furnishings for every child, but instead changing the surroundings and accessories to reflect the child's individuality, therefore I would consider it bad practice to purchase a pink, blue, or gender specific crib. The only exception would be for my clients who have more than enough money to burn and are less concerned with cost than showing off their new bundle of joy's space.
For mom's comfort I like to specify either nursing chairs, or for those who bottle-feed, a comfy rocker/glider (some nursing mothers like to have these chairs as well). Dads are fond of the gliders too, and I will get requests to accommodate more than one in a room so he can share the experiences with his spouse.
Baby items have become big business, and accessories and bedding can be found everywhere. If you're looking for value, you are no longer given two or three options, there are thousands. Quality items are also abundant, but becoming more boutique store items, as cheaper alternatives have started to affect their niche markets. Baby bedding and curtains can be purchased to match, but in this regard, I still like to switch it up and add a designer's touch by using coordinating (not matching!) fabrics. Accessories for babies' rooms can go from art to decals on walls, knickknacks or vases, toys, and mobiles.
