While there are in fact a number of songs you can play with simply the Em and Am chords, I know you're going to want a little bit more than just that. If you're still working on those first two chords, that's okay, they might take a bit to get comfortable with. Bookmark this page, work on the chords for a bit, and come back when you're ready for a few more. I'll still be here!
Now many people are going to ask about other brands, like why don’t I suggest Gibson guitars? It really is a personal taste thing, and it’ll ultimately depend on yours. Perhaps by the style of music you play or the artists you admire. For me, Fender guitars represent the best in quality and feel. Many Gibson style guitars have fatter necks, bigger frets, are heavy, and feel and sound “muddy” to me, whereas the feel of a Stratocaster– light, slender, classic– feels, plays, and looks fast.  :)
Justin Sandercoe has thought long and hard about how to teach people to play the guitar, and how to do this over the internet. He has come up with a well-designed series of courses that will take you from nowhere to proficiency. I tried to learn how to play years ago, using books, and got nowhere. I've been using Justin's site for just over a year and I feel I've made real progress. What's more, Justin offers his lessons for free - a boon for any young player who has the urge to play, but whose pockets are empty. I've seen and used other sites for learners: none of them offer as clearly marked a road as Justin does.
A child as young as 4 can begin to learn if they are really motivated and have a patient, creative, and devoted teacher. However, we've found almost all kids under six are too young to benefit from formal guitar lessons, as they require dexterity and levels of concentration children their age can't provide. That being said, lessons do not need to be formal right off the bat, and can just provide a fun introduction. Also, your child may benefit from using a ukulele to start, as it's smaller and easier to learn, but very similar instrument.
When you play the right note or chord, you will hear it. It will be a pleasant sound, it will be clear and won't have any blocked string sounds (unless it needs to, but you'll get to that later). To play a note or chord correctly, you have to get your fingers in the right position and press as hard as you can on the frets; it will become a habit if you practice enough.
