Light fixture is burning out bulbs in about a day

For some reason a light fixture in a downstairs bedroom is burning out bulbs in 1 to 2 days. The fixture is in a 3 year old's bedroom so there is a small chance he may be up to something down there that's causing the problem.

I was hoping I could get some tips on diagnosing whether there is any problem with the fixture itself. I'm not even sure what tool to use to start.

Any help is appreciated!

If it is a standard incandescent bulb you may need to check the pin in the center of the socket,to do this shut the power off to the fixture either by the switch or the circuit breaker or both then look into the center of the socket and with a pair of needle nose pliers or a small screwdriver pull that tab down a bit to make a better connection with the lamp base, reinstall the lamp ,turn the power on,did the base of the lamp look burned?

What type of light is it, incandescent or fluorescent? If it's incandescent there is very little the fixture can do to cause the bulb to burn out. It may not may contact but if the bulb works for several days then the bulb actually burns out I'd suspect cheap bulbs. 130 volt bulbs may hold up better. If it is a fluorescent fixture it's possible that the ballast is bad.

30 yrs ago I had a hallway light that the bulb would never last a month, sometimes only a week After I replaced the fixture, the same brand of bulbs would last a year or two. Someone told me they thought maybe the old fixture had a bad ground, all I know is replacement fixed the problem.

Many fixtures don't have grounds and in any event grounds are not needed to function. However many bulb holders have riveted wires which could make bad contact. If you really like the fixture you could try replacing the bulb holders.

I'd start by replacing the socket. The rivets in the sockets loosen over time and get corroded.
