I'm am EXTREMELY against spanking in my own household. Everyone says I'm going to spoil my child but I believe that they are wrong. I was also told that my child wouldn't sleep through the night or self sooth if I didn't let her cry it out. I refused to let her cry it out and used my own (in my eyes) a much more nurturing, loving method. I have a baby that has slept through the night at 2 1/2 months and has put herself to sleep at about 3 months or so. I believe this is because she goes to sleep content and happy...
I will discipline consistantly, but I will not spank.
Joshnaz - You could do other things besides spanking. Google "attached parent forum". That will give you a lot of ideas on how to deal with a toddler besides spanking.
