M.,
it is an interesting question to me as I learned about little people before I got myself one, from visiting my elder brother who had 2 kids: a 6 months old daughter and a 16 months old son.
As soon as I arrived, my brother had to go on a business trip and his wife told me: oh, cool, we are leaving together, and you babysit with kids! (I was 18, btw.) "Wait-a-minute", I think, "I haven't seen babies so close in my life, this is my very first experience!" and I say to her: "NOWAY!" She says "nothing to be afraid of: they are pretty much self-sufficient, you only need to help them with food and potty." I was so bewildered, couldn't even speak, so she added: "and if anything, Indrek (the elder son, 16 mo.) will guide you through, he'll tell you". I finally opened my mouth: "He cannot even talk!" Mommy lifted her eyebrow: "Okay, if you will be REALLY confused, then here is the book!" And sure thing, in 2 days they left for a week. Here I am. Here they are :), my little niece and nephew. All the floors and carpets are washed clean and vacuumed, all the dangerous objects, like scissors knives needles and such are locked in the upper shelves, keys hiding in safety. Toys are all over the place, including kitchen. So, as you say: it IS a SUPERYARD :) !
Anneli, the 6mo. niece is crawling EVERYWHERE, likes touching my toes, picks up toys, if interested in one then sits down plays, then moves on to explore. Indrek is walking, petting his sister, hugging my legs, and trying to help with carrying stuff around from place to place. This was one happy childhood for both of them (they are adults now). I learned tons, and ever since wanted my own kids.
Now, the suggested emergency book that I certainly started to read in the evenings, was Benjamin Spock. Very unusual, and inspiring. I do not at all agree with all his methods and approach, but he was an eye-opener to me, showing that there are millions of more angles how to look at the kids, how to deal with them, and how they perceive the world.
One thing i understood and it helped me to raise my kids in a very happy environment was this:
I leave them their space, not invading into it until it is really necessary. if the baby and later a toddler is allowed to explore the world, they will entertain themselves and will be extremely curious throughout their life. The task for parents remains at all times: keep them safe. How to do it, you just asked.
Option one: remove all the potentially dangerous stuff, and fill this safe space with objects that the enjoy: say, pillows, stuffed animals for coziness and toys appropriate for their age.
Spock suggests option two: do NOT remove dangerous things, and if they get hurt, let them learn what hurts so that they quit doing what hurts. If they touch a hot iron, on the third burn they learn this is 'aoui' and do not come close to it anymore.
I did not use that method, but I've seen families who did...
it's up to the parents to make choices of course.
one last sidenote for you, M.,
if you start creating a house-size safe superyard for our little guy, remember to watch what he learns to do, to prevent next potential dangers: as soon as he figures out how to climb chairs, make sure the next level (chair) does not bring him closer to the next dangerous areas. I moved chairs to the middle of the room (some clutter, but then my sons did not climb up higher from the chair to the table and to the shelves :) ).
They also soon learn how to TURN KNOBS: watch for the gas or electric stove then!!!
Once my year-old son figured out how to MOVE the furniture around, even pretty heavy things, I blocked some areas or put something heavier on the top of the night-table, for instance, so he couldn't move it, but i left him one empty night-table and he was moving the thing around, developing big super-boy muscles.
Also, you need to develop a keen ear: listen attentively to sounds, if he is in a different room: if it is usual noise, it should be okay, if it's totally quiet, he got busy: I would go peek from the door what's up without interfering much into his exploration experience, but making sure he's safe.
This is also how children learn to be focused. If they are not interrupted while being engaged with something, it's good to allow them to be totally focused by not interfering. They will be done with that activity, and then move on, and they certainly come check on mom's and/or dad's presence million times: the younger, the more often they come to give a hug, to get a hug, to see they are in mom's space. (you notice this on the beach: pay attenmtion how often and how far little kids move away from mom, how often they come back to mom to just touch her or catch her look, and how long they will stay in the closer mom-space, to take off again to go play farther. You will be surprised what you find out, and then use it for your own communication with your little son :).
The very last sidenote: if you allow him to crawl EVERYWHERE you adults all need to learn quickly that you have one super-creature under your feet AT ALL TIMES as you will never know when he will appear BEHIND you: step consciously, be careful with hot water, objects that you carry: he will be always in the most unexpected places!
Oh, and in the kitchen and otherwise, ALL THE HANDLES of all the pots and pans need to be INSIDE the area of the surface of the stove, table, shelf: make it a rule for yourself, like a habit. For example, while cooking, turn ALL the handles inward, at ALL TIMES, because he is growing, and one day he will stand on tiptoes to grab the pan-handle: if there is a hot oil in it, the trouble might be big!!! This is 'aoui' that we don't want them to learn on sad experience.
If anything else, write me on ____@____.com,
I might remember something more, but as for now, this is my experience. Good happy days for you all, and take care!!!
