If I had it to do all over again, I would let my kids take their lumps as kids and not bail them out. If the homework was left on the table, then it should be late; I would not rush it to school. Consequences as a kid are hard and bring tears.  They think you're mean and don't love them. Consequences as an adult often bring tears, unemployment, repossession, etc. Which is easier to bear? As a parent you can take the time to TEACH and TRAIN your child and the tears are the glue that makes the lessons stick.
