E.g. what does "over protect" mean? Is it ok to let your 2yo climb on the climbing things at the playground, even if they are for bigger kids? Is hovering to catch him/her in case of fall overprotecting? What about climbing on trees? And Fences? At what age exactly is it ok to let your kids go to school or come back on their own?
Or, "read to them". Is one story at evening enough? one booklet per kid maybe? 2 each seems better, but then, probably it's better to read them something in the morning too etc.
Going back to the original proposition, most likely it won't matter too much if you read 1 book a week or ten stories a day to your kid, s/he will love you anyway, and as long as you are not abusive and keep them fed and clean, you'll be a good enough parent, which is the best one can hope for.
