Hmm.. I don't know about not helping at all. I do agree that "walkers" can be detrimental to gait patterns, but I don't see the harm in letting baby hold onto your fingers for balance. My ds2 was so so close to walking on his own for a couple of weeks when I started letting him hold onto my fingers to practice. I wasn't afraid of helping him, I just hadn't really thought to try it. He got so excited and proud of himself every time, and it seemed to help the motor program to really click, and he was off on his own not long after.
I agree. My dh and I always let our babies hold our fingers for the simple reason that they loved it! I remember our oldest dd when she was a year old holding on to both our hands while we were on vacation "walking" down the sidewalk and screaming with happiness. My dh would always say, "Can't do this at home." (Of course she could, but for some reason she loved being helped to walk in novel places.) My kids were late walkers and liked some help.
Also, my babies preferred to be upright while they were awake. I did have walkers with my older two (saucers hadn't been invented yet) because despite their spending a lot of time sitting or standing on my lap, I did need to cook, take care of other children, work with clients, work in the garden, fold laundry, rest once in a while. My youngest baby had reflux and was only comfortable when completely upright while she was awake. A saucer was the perfect solution for that when I was working in the kitchen, folding laundry, seeing clients in my home ect. Also, I spent a lot of time in our garden and she would eat plants (tomato and pepper plants have poisonous leaves) so I had an old saucer for our garden, so she could see what I was doing. When she wasn't "helping me" plant seeds (she planted her first seed, pumpkin seeds at about 7 months old) or picking, she would be happily in her saucer, out of harms way while I worked in the garden. My husband even made me a "nursing chair" for our garden. It was like a Adirondack chair, that he made from scratch, so I could nurse the baby in the garden.
We have a whole acre of property, with the best sun at the back of the property, so our garden is around 300 feet from the house. So, unless she was sound asleep (and I was using my..... baby monitor) my babies needed something to keep them off the ground and away from plants and bugs that might hurt them to the hours a day I spent in the garden.
I think a lot of these gadgets depend on your lifestyle. When you spend several hours a day in your garden (and the babies attempt to escape the sling every time you bend over, not to mention bending over repeatedly with a 25 lb baby in a sling is bad for your back) things like baby monitors (for naps and in the nighttime) and baby saucers do come in handy.
