I just put them in nice looking casual outfits (e.g. khaki pants and a polo shirt). I tried to keep them in colors that look good together, but nothing too matchy. We tried to get photos of the two boys together last summer, but Connor wasn't having any of that. He was super cranky and we could barely get a smile out of him, let alone have him pose cutely with his little brother. We ended up just getting separate portraits of the two boys. Hopefully next time it will go better.
