I've had hamsters before. Always one at a time and always a male. Trust me, stick with a male hamster. Females can start reproducing within a few weeks of birth and I did not want to risk the cannibalistic factor. Hubby had some before we got married and they just multiplied like crazy. He would keep the healthy young in a kiddie wading pool and he fed them Old Roy dog food--he couldn't afford the hamster food. He started with 3--one male and two females. Within 3-4 months he had over 100. He would give litters to a pet store when they were weaned because he could not care for all these. He did get many of them re-homed, had a few that escaped, and unfortunately at the end one got sick and nearly all of them died.
Get a male.
I had one hamster get "wet-tail" and it died. This was a long haired teddy bear type. I never got the long-hair ones to live long. I had better luck with the normal, non-exotic short tan and white hamsters. Make sure you research wet-tail so you can be prepared. It can be deadly.
Hamsters are typically solitary critters. They like to be alone. If you want multiple animals, you would be better getting gerbils. They enjoy companionship and play during the day. But I don't think your son wants gerbils. With each of my new hamsters, I would handle them the first week or so wearing some good fitting garden gloves. They can get nippy and break the skin. The gloves allowed the hamster to get used to being handled, then when he wasn't biting as much, I could get him used to my scent and bare hands. I hope you have good luck. Some hamsters can live several years, others sadly only a few weeks. They are fairly fragile creatures.
