Shooting in Raw and Jpg?

So I'm a newbie just shooting photo's of my daughter, and some outdoor shots. Right now I'm shooting in the highest setting both RAW+JPG. I figured it would be ideal to have the RAW's if I ever needed them.

Not sure if shooting in RAW and JPG slows down the camera or not. I know photoshop well and have a copy of lightroom but haven't used it much.

I've read the pro's and con's of RAW vs. JPG but I'm looking for a simple answer.

What do you all shoot? Raw? JPG? RAW+JPG Together?
