Best toys in the 80s and 90s? No way. They were all starting to be full of batteries and noisy.
All the best toys are those that allow kids to use their imagination and have as few as possible moving parts. Building blocks, legos, sturdy kitchens that don't mimmick sounds, soft bodied dolls that don't do ANYTHING except maybe roll their eyes and friction motor cars, not battery operated ones.
And why did this have to be moved to parenting and pregnancy? This should be a general discussion if you ask me because it's asking people to think back to THEIR childhood, not asking for kids now. Just my 2 cents. Sometimes I think things are switched too much.
Does anyone remember those dolls that had large gems for their torso. Their legs, arms and head could be pulled out (to play with the mini doll, like you would a polly pocket but bigger) or you could tuck their heads, arms and legs into the gem torso, attach the gem to a stretchy band and wear it like a bracelet? They also had ones that converted to a ring and necklace. Those were the best...circa 1986.
