These tricks are currently working for us. (Most of the time, anyway.)
Trick #1 - Do not take an object away from the toddler. Instead, ask the toddler to hand you the object, then thank them.
Trick #2 - Don't tell the toddler "no, you can't play in the fridge/dishwasher/makeup drawer/trash can". Instead, tell the toddler that you are "all done" and ask them to help you shut the door/drawer/lid, then thank them for "helping".
Trick #3 - Do not eat/drink things in front of your toddler that you wouldn't want them to have. Instead, be prepared to share everything. Or have something special just for them that they don't have to share with you. It's only fair.
Trick #4 - Don't ever walk away from your needy/separation anxiety-ridden toddler. Instead, tell your toddler where you are going and that you'd like them to come with you and help. Then if they don't follow, at least it's their choice.
Trick #5 - Distract. Then distract again. And then distract some more. Eventually the toddler will forget what it was you were initially trying to distract them from.
Positive reinforcement, saying thank you, and hand clapping for a job well done are working wonders in our household these days as well.
