I've done both the trailer (still do that) and the child seat behind mine, and well actually both at the same time. My son loved both. He was probably two before we started in child seat - actually I know he was because I didn't get the bike until then. He loved it. I weighed about 240 at the time and didn't have any problems, but my bike was pretty tough - not a road bike. Once he started growing a bit, he started to get more uncomfortable behind my big posterior. The trailer was nice - room for him, his brother, and snacks, drinks that they might need. I'd say it really depends on the type of riding you do with him. On the MUP or in my immediate neighborhood, the trailer was definitely the way to go. Riding in traffic, I preferred him on the bike with me. I imagine if I were doing a mountain bike like trail, I prefer him on the bike due to the amount of room.
Good luck and enjoy riding with your child.
