Directed towards the OP,
I am probably going to rattle some cages however you did post your question on an open forum...
I will state first of all that I am a parent as well...
This aside I have worn many hats in my lifetime, and one of those hats was a certified Early Childhood Specialist and a infant/toddler teacher/Case Manager with an emphasis in special needs...
While I do like the idea of allowing your child to explore their environment and make toys out of objects that are NOT TOYS is excellent it allows them to find uses and see what works ( Math, science, cognitive and dramatic play) As well as literature!!!!! Kudos to both you and your spouse..
Regarding food? Ummm, it is okay later in life to allow processed foods to occur in your childs diet however at this age healthy eating habits should be established...introducing kid friendly veggies and fruits is essential for your childs development...unless a multi vitamin is being administered.
At 1.5 your child can eat table food and does not need baby food anymore..
Regarding baby proofing your home? This should be common sense..
At 1.5 your toddler is somewhat sturdy however still getting the handle on depth perception and is prone to fall..
Providing a safe environment should be mandatory...It means very little to me when individuals state "A child will adapt to their environment" by trial and error...
As a former validator for Head Start I had to ENSURE that each site was appropriate for children and these were not "homes" this is where ones children spent a portion of there day!
So yes, child proof ties to close toddler level cabinets where household chemicals and sharp objects or utensils are kept are mandatory.
Gates guarding stairs are mandatory unless you are 1 step behind your child at all times..
CPR? PRICELESS! I useto priovide infant/Toddler CPR and first aid for my parents free of charge...
True story? 4 weeks ago my 2.5 year old niece was sitting in her high chair and ate a small piece of apple and started choking on it..she was turning purple and making gasping noises because the apple was trapped in her esophagus and my 20 year old nephew whom had taken CPR last semester was able to assist and save her!
With so many outside influneces in our world that our out of our control one would think that WE as parents would do our best to take care of the little things that are within our control in order to make our children safe..
