Finding a rabbit that really likes being held and cuddled could be a challenge, especially with the smaller breeds. Generally speaking, rabbits aren't cuddly and the smaller ones especially tend to be hyper, and they aren't always the greatest choice as a pet for young children.
Having said that, the following breeds might be worth looking into. I also recommend you take the time to find a good breeder, not a pet store rabbit. You can find pictures of all 47 ARBA-recognized breeds here, and in most cases clicking on their picture will take you to that breeds' club webpage.

As a general experience, bucks tend to be more docile than does, but not always. If this is strictly a pet you might look into getting it spayed or neutered.
American Fuzzy Lop: Generally gentle, but a wool breed. Will shed (a lot) and need frequent brushing.
Dutch: Slightly larger, 'sturdy' rabbit. Very common. Most of the ones I've known have been gentle.
Havana: Similar to Dutch from what I've seen. They may also shed less than Dutch.
Himalayan: Himis are considered THE starter rabbit for youth showmen. They are tolerant and docile, and are often called 'velcro bunnies' because they'll just cling to you and chill out. A lot of people don't like them because of the pink eyes, but if you can get past that they are commonly considered the gentlest breed.
Holland Lop: Roughly the same size as a Fuzzy Lop, slightly less shedding, more hyperactive in my experience.
Mini Lop: Slightly larger, generally very gentle. Sheds. A lot.
Mini Rex: Usually good buns. Good lines are important due to the prevalence of sore hocks in the breed, where there isn't enough fur covering the bottom of the feet which sometimes leads to open ulcers.
Polish: Netherland Dwarf size without as much attitude.
