When did you give your LO rice cereal?

How old was your LO when you first gave them rice cereal? Did you give it to them in a bottle or by spoon? Was it recommended by your doctor? 
Or- how old is your LO and why have you choose not to give them rice cereal yet? When will you give it to them? Bottle or spoon? 
This is a very touchy subject in our family. Everyone has tried pushing it on us, and I'm against it at this age (7 weeks) because he doesn't have reflux and is gaining weight perfectly. I also want to give it to him by spoon instead of bottle whenever I feel like the time is right. But I'm just curious on how it worked for other babies and I wanted to hear from other moms!
