I definitely would not recommend a netherland dwarf, a dwarf hotot, or a britannia petite (the smallest true dwarf breeds). They can be very hyper and many lines tend toward aggressiveness. Some are very sweet, but i's hard to get away from the hyperness. Personally, I ADORE netherland dwarfs and britannia petites, but it definitely takes a special person to deal with them.
Here are my recommendations...keep in mind that weights listed are accepted show weights, and a pet quality one could be heavier or lighter than the standards.
Mini rex I have found to be GREAT. They are usually sweet, and their plush fur is just perfect for cuddling.
They range from 3 to 4 1/2 lbs.
Holland lops tend to be either very hyper and nervous or very calm. There is not as much in between as I have noticed with other breeds. Pick a male if you go with this breed. Their maximum show weight is 4 pounds (no minimum, though most are 3 pounds and larger).
Mini lops are usually very sweet, but they are a bit bigger; running from 4 1/2 to 6 1/2 pounds for show weight.
If you don't mind red eyes, I would highly suggest a Himalayan. They are not only exceptionally calm (I call them the "bombproof breed"), but they are very good sized as well. They range from 2 1/2 to 4 1/2 pounds.
Havanas are a little bit of a plainer looking breed, but they are generally very sweet. They range from 4 1/2 to 6 1/2 pounds. I know of several breeders who, despite their plainer look, just adore them for their temperament. One breeder I knew sold out of holland lops because her havanas gave her so much less trouble.
If they have time for grooming once or twice a week, a Jersey Wooly can make an excellent pet and tops out at a maximum show weight of 3 1/2 pounds.
I'm not overly enamored with Dutch. They are cute and can make good pets, but they are notorious for spraying (definitely get it fixed whether it is a male or a female as females can spray, too), and they can tend to be hyper. It may be due to the fact that netherland dwarf was introduced into the breed a while back, or it may just be that the competition in show lines is so tough and good markings are so hard to get that a quality rabbit is more important that a good temperament. They can be between 3 1/2 to 5 1/2 pounds.
There may not be a breeder in the area, since the breed is not showable yet, but mini satins would be another breed I would recommend to a family looking for a small, sweet breed. They are a cross between polish and satins. They stay pretty small and they have a lovely extreme shine to the coat that is like satin, the fabric. I had them for a while, but they were taking so long to get recognized, and I really needed to focus on my main breeds so I sold them. I really like them, though. Then again, I'm a sucker for a little, round-bodied bunny like this breed (and mini rex).
If you can convince them that large rabbits can be great, french lops are AMAZING! They can be like dogs! If you litterbox train them, they will just run around the house and hang out with you. They are huge, but they are oh-so-sweet! I was sad when I had to sell my frenchies, but I didn't feel I had the room to really work with them properly and give them the space they needed. But really, having them is like having a dog that doesn't bark, doesn't have to be let out to go to the bathroom, and isn't going to bite your ankles.
Plus they are almost kid proof because they are so big they can take some more roughness than the smaller breeds can.
