It is fascinating to me to see, now that my two girls are approaching maturity, how much of their characters they have retained even from babyhood. I won't give too many details, to protect the innocent (grin), but here's a few examples.
The Musician has always been extremely laid back. I like to think my good parenting helped with this, but she was an extremely easy baby to care for. The only times I ever remember her getting upset as a baby was making her do something that she didn't want to do. By this I mainly mean things like when I held her down while a dentist corrected her frenulum (she was tongue tied like her mommy.) Let her hang out and play with her toys, and she was fine. She also decided around the age of two, that she was not a girly-girl, and she still isn't.
The Dancer, on the other hand, has always been rather active. That's why I started her in gymnastics in the first place, to positively channel her energy. You might remember that her first nickname on my blog was Wild Child, and she has always deserved it. When she got a little older, she chose ballet for herself, and now she is taking three dance classes per week and assisting with another dance class, and loves it. She spends a lot of her time bouncing and dancing around the house.
I also love seeing bits of myself and Mr. BTEG in some of the things they do, things that seem more inherent to their natures rather than learned. I tried, for example, not to let my picky eating create bad food attitudes for the girls, and fortunately neither of them learned food dislikes from me. Sometimes I wonder if the nurture part of the whole nature/nurture balance consists mainly of teaching them polite manners and things like respect for others. Other than that, they really seem to have chosen their own courses. Of course, Mr. BTEG and I decided before they were born that we wanted to give them free reign, up to a certain point, to develop and express themselves. I know that sadly a child's personal growth can be messed up by such things as an overly strict or overly lenient parent.
Lastly, about the tongue-tied thing. I always thought, because it passed through my maternal grandfather all the way down to my daughter, that it had a strong genetic component. I only know of meeting one other person who was tongue-tied. I find that interesting. I did discover recently that Jeremy Brett, mainly of Sherlock Holmes fame here in the States, also reported himself as tongue-tied, although different sources seem to describe it differently. He was also bipolar and left-handed (they used a "hand double" during scenes where Sherlock was writing although he is shown during one episode boxing left-handed.) I would have loved to meet another tongue-tied, left-handed, bipolar person!
