There's generally a good deal of wiggle room when it comes to parenting styles.
Whether some parents choose to adhere to a strict schedule when it comes to naps or snacks, or if they'd rather their kids simply snacked when hungry or slept when tired, not every family will make the same decision because there's no one right choice.
The same can be said of correcting bad behaviors in kids — but when it comes to using corporal punishment, or spanking, science is increasingly showing that it might be time to find alternate methods.
