Follow up on Adornment and Toddlers

11 My son, do not despise the LORD's discipline
    and do not resent his rebuke,
 12 because the LORD disciplines those he loves,
    as a father the son he delights in. Proverbs 3:11-12

My husband and I are having trouble with this. I don't quite understand how to approach discipline with a joyful attitude (we don't get angry but we are not necessarily joyful about it), especially if my toddler hits and kicks us. We use a low firm voice when correcting and then we spank. One night my husband had to do this over and over and over again. I was crying out to the Lord for wisdom, for my husband and my child... if this was really the right thing to do or how we were to approach this? Over and over again my child continued to hit and kick after being corrected/spanked.. my husband was not angry but he was firm. We are both new at this, and I'm wondering in this example of my 2 year old son, are we to correct/spank until he stops hitting/kicking? What should we do?
