You know.....the one thing I loved so much about my dad was that he was so different than my mother.
My mom sewed all my dresses, made me sleep with pink rollers in my hair and was very proper about things.
My dad took me fishing and let me get dirty. He taught me to work on cars. I was like a surgeon's assistant handing him his wrenches and I knew all the sizes of his sockets. I learned to hold the flashlights in just the right spot.
I'm all about culture and museums and things. I grew up in the San Francisco Bay Area so I was exposed to many, many things.
It was the simple things I remember most about my dad, God rest him. He had a wonderful sense of humor and we could do yard work together and have a blast. He was always the one who stayed by my side when I was sick. He would stay up with me late at night on the weekends and watch "Creature Feature" with me. The showed old, actually pretty horrible scary movies which didn't really scare me at all.
Dads have different ways with their kids.
I think that sometimes moms just have to relax, let it happen, and not interfere too much. I, personally, think it's really great for a kid to get the best of both from each parent and frankly, you never know what the child finds to be special and important in it's own way.
I don't think you should interfere too much. Your husband loves to read? That can't hurt your son. He will pick up a love of it too.
Don't put pressure for them to DO, DO, DO all the time. Let them work it out for themselves. I have a son. His relationship with his dad is way different than his relationship with me. As it should be.
Just my opinion and no offense.
