Practice at least 20 minutes 6 days a week. Consistent practice will allow you to improve your guitar playing skills over a short period. Taking long breaks and not staying dedicated will wear away your muscle memory and delay the development of your skills. Instead, dedicate 20 minutes to an hour of practice throughout most of the week. During practice, you can either run different drills or you can try covering a song.
Learn how to transition to different chords. One way to become proficient quickly is to learn how to transition between the various chords quickly. These transition periods are often the hardest for beginners to play when they are starting off. The more you practice between switching to different chords, however, the better you'll get at doing it in songs. Practice switching between open chords like G, A, E, and C. 
The simplest answer and the one that no student that ever wants to hear is practice. Changing chords is the process where many beginners fail, and quit. But after that, the rewards will be simply impressive. There are a few tricks to get a chord transition to happen faster. Use a metronome: Set it on four beats and set it as fast or as slow as you want. Then get a chord in your mind, say D. When the metronome reaches its last beat, press down the strings. When it happens again, strum it and let it free. Then again. Do this 10 to 20 minutes a day and in less than a week, the chord progression will begin to sound much better.

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.
Electric tuners are easy to use and very accurate. Hold it to the guitar and pluck the high E. The tuner will tell you if the guitar is "sharp" (too high) or "flat" (too low). Pick each note and tighten the string to make it go higher, or give it some slack to lower it. Make sure the room is quiet when using a tuner because the microphone on the tuner can pick up other sounds.
