What is "now" is likely not "what will be".
Dh and I both throught spanking was just part of parenting, until I realized what it had done to me and put the brakes on. Read a bit, found GCM. Got pregnant.
DH? He was Mr. Physical Discipline, pro-circumcision, some CIO is fine, vaccines re a probability...
Yeah. About that.
Everything up there he is now the polar opposite of. Course, he still talks a big game sometimes (being male and southern and all), but I could no more see him raising a hand to a child than he would kick a puppy. I suppose some of it is that he trusts my research, and knows I read everything I could gets my hands on while I was pregnant. *shrug*
I wouldn't fret too much. You may find he changes with time and a baby, but if not, just stock your own toolbox so you can help show him the better way.
