What do I need to baby-proof my house?

make sure your wires are all bunched together and out of baby's eyesight. They sell a lot of great babyproofing stuff at onestepahead.com I would really suggest checking out their site.. they have lots of things on there that you wouldn't think of till it was too late!!
wires.. stove.. steps.. furniture that can be pulled over.. blinds and cords.. plugs.. etc...... doors too! I got my friend a great door lock that works for her hard to close french doors!

Cabinet locks. He will soon discover the joys of opening the doors and pulling everything out.
Outlet plugs. You can't watch him every single second and that's all it will take to shove that little thing he found on the floor into an outlet.
Gates over any stairs.
Toilet locks. Again, you can't watch every mintue and kids are FAST. Soon, he will be pulling to stand and water will be a major attraction.

Oh, if the knobs on your stove are on the front instead of the top, you'll need covers for them at some point. You can also get oven door locks and fridge door locks. My daughter never tried to open the oven (that I know of) but the fridge is a LARGE attraction. At this point (2.5 years) she knows HOW to work the lock but can't reach it. Without that, I know she'd be in the fridge all the time, hunting for strawberries and other tasty things to eat.

put plugs in all the outlets even the ones that you think they cant reach cuz ohhh they can. we put locks on all the cupboads and drawers in the kitchen. and i just basically keep all the doors closed so the only rooms my daughter can get into are her room, the kitchen, and the living room.

closing doors helps alot...or baby gates. all outlets should be covered. sharp edges on low coffee tables or entertainment areas could be padded. some people baby proof the cabinets with clips, and do the same to the toilet seat...but really you can just keep those doors shut

i dont believe in baby proofing other than the small objects that they can choke on.
you should teach him/her what to and not to touch.
my opinion.

put covers on outlet and if you can buy a baby gate for your kitchen.

anon he is six months old and crawling he is going to get into shit and could possibly get hurt in the process she wants to protect her child. she isn't going to put him in a damn bubble. when he is old enough to know what no means or that he could get hurt thats different

Don't forget about cleaning products, cosmetics and any other chemicals you have under your sinks, in the kitchen, laundry room , etc. I put mine on a high shelf above the washer and dryer. A locked cabinet works too. (I also bought this great locking cleaning caddy at onestepahead.com...its fantastic!
