My children are 21, 18 and three. They are all very close even though there is such an age difference. I don't remember doing anything to ensure a bond between them, but I tried to continue to do the things that we had always done even when the baby was small. My oldest played high school baseball and football and we just bundled the baby up and put him in a front carrier (to keep from having to pass him around for everyone to breath on) and never missed a game. Babies are pretty durable, so just keep on trying to enjoy the things that you do now with your child. There will be places the baby can't go, but that's what baby sitters are for. Staying involved in your older childs life hopefully will keep any resentment away.
