• When cooking use the back burners as much as possible and always turn pot handles to the back of the stove.
• Oven doors get very hot to the touch when they are in use, make sure your child can not get to the oven to prevent what can be very painful burns.
• Make sure all knives and other sharp objects such as scissors are safely stored out of reach
• Secure cupboards with safety latches, there are several styles available and you are sure to find ones that will work with your kitchen decor.
• Keep all small foods like beans and nuts out of reach to prevent choking hazards. While preparing food make sure if you drop something on the floor that you pick it up immediately. Little kids love to find things on the floor and are almost guaranteed to give it a taste test.
• Tie plastic bags in a knot to prevent suffocation.
• Remove all small appliances and unplug them to reduce temptation.
• Secure all cleaning products and other chemicals high out of reach to prevent poisoning.
• If you use a table cloth make sure your little one can not pull on it and empty the contents if the table down onto themselves. Try using placemats instead until your child is older and it is safe to bring out the table cloth again. 
• Ensure that your highchair has a safety belt and use it evertime your child is seated in the highchair.
• Make sure the chairs and highchair cannot be used to climb up onto counters or to access windows.
• Teach your child there is a "no go" zone around the stove and oven. Try placing a mat on the floor as a visual indicator of where they are not allowed to play.
• Keep your dishwasher locked at all times and the soap out of reach.

With those relatively simple things you can help make sure that the kitchen is a safe place to be for your child and the reast of the family too.
