Our 16-year old son is an only child. When he was around five he said he would really like a brother or sister . . . or maybe a dog. He got the dog! Seriously, we have had discussions about how he has felt being an only child and he is very much okay with it. He sees how his friends who have siblings fight all the time and how it seems that there's always someone who doesn't get as much attention as the others, so he's just fine. We do have his friends over often - almost every weekend you can find 2 - 6 of his friends here hanging out, and now that they are starting to drive (yikes!), there can be guaranteed a couple days of the week that they are here, too. It hasn't always been easy; we have had to make an effort to make sure his friends get here - we live 15 miles outside of town and he went to a Charter School, which meant that most of his friends lived in town or outside town (the other side of town, not our side!), so there was often lots of driving, carpooling, planning that needed to be done. We also have kept him busy with activites (he's into music, not sports) and some volunteer work. He is somewhat spoiled - or is it well-loved? He doesn't get everything handed to him. If he wants something he needs to work for it - either working for neighbors or doing work around our property. Many of our friends have told us that he does not seem like the typical "only child", that he's very down-to-earth, helpful, friendly. We have never made a big deal about him being an only child and we have never felt bad about it. I think if you start worrying about, feeling bad/guilty, that's just going to create problems and make him feel like he's missing out on something. Simply acknowledging his feelings would most likely suffice - "I know sometimes it seems like it would be nice to have a little brother" or something to that nature. The funny thing in our family is that my husband is an only child and I have a brother who is 12 years younger than I am, so I was an only child for quite some time. Niether of us ever remember being too upset by not having siblings!LOL! And we seem to have turned out pretty well - have good jobs, long-term friends, have been together 20 years. I think it's normal for kids to want siblings, especially when they see friends who do, but I also think, if done right, it can be very beneficial to the child. Just don't make him the focus of everything. We have always made it clear that he is a part of the family, not the center and life does not completely revolve around him, that others need time for themselves to do things they want, and that we are not here to wait on him hand and foot (although this one seems to not really have sunk in as he still tries to get away with it - doesn't happen very often, but he still tries). Okay, I'm starting to ramble so I'll stop here. Only children do not suffer from it - only if it's made into a big deal about how they're deprived will it effect them. Good luck!
