spanking!....

my dad gets on me because he feels I don't spank my son enough. I hate spanking him and I get so scared that someone will think its abuse (even tho where I live it legal to spank). I don't want anyone to think I'm a bad mom because I spank. but my dad says if I don't spank him his behavior will only get worse and I'll end up with an uncontrollable defiant brat. idk I dont want him to be an awful spoiled brat like so many kids now these days but a lot of people are putting the word abuse on spanking witch I don't agree with but I don't want someone to tell people I abuse him because I spank him.
