Hi A.-
Yes, there are those of us who have rocked ourselves to sleep throughout the years. I am one of those people. Apparently, I too, started when I was very little, as my mother would tell me she would find me in my crib all the way down the hall because I had rocked through the night!You won't believe this, but I eventually gave it up just prior to going to college! Wow, I bet I really worried my mom. The rocking motion did(does) help me to become sleepy at night when I am anxious or have a stomach or back ache. Yes, I have found I can revert back and rock at night maybe once every few years for one evening (usually lasts a few minutes). And yes, I am married and I don't think my husband has ever had to deal with it. I have found if I do rock in bed, I usually don't feel well, so I turning in earlier than he is. It has just never been an issue. Mother said I did wear out a few baby cribs though!!!!
I will let you know, be prepared, as I do find that I sit and rock back and forth a lot at the kitchen table while reading the newspaper or watching T.V. or listening to music. Again, I think it is tied up with keeping my stomach "quiet", although, as I am doing it right now, it also just seems to relieve stress. I do have stomach issues (nausea, generally icky), but I have also been having stomach issues this evening. As a child, as a passenger in the car, I also rocked quite a bit (almost from the moment I got in the car); still do as a passenger to some degree, as an adult. It helped when I started to drive.
I haven't found any long term side effects and I think I would have noticed by now. Just be aware that this may crop up as he gets older when he is just sitting around at the table or in the car. I think if I hadn't rocked all the years we traveled in the car, I would have been a lot more car sick! It definitely helped me there.
Good luck!
