Umm, I hate Plastic and electronic toys, there are other words to say other than "no" and ways to promote sharing without forcing a child to do it.
I prefer simple wooden toys, books, art projects and sensory tables. I use the word "don"t" or "stop" while redirecting and explaining something. I rarely use "no." You can explain how nice sharing is, explain that it makes other ppl happy and that when they are done playing with a toy they must allow another child a turn. I also firmly believe some toys don't need to be shared, like a special lovey or teddy bear.
I think it's great you are looking for an alternative position since you don't have the same parenting views as your MB. Good luck.
