You are doing what you have to do to keep your son safe. And oh do I feel your pain...literally, when it comes to the back pain! I am going through a similar thing right now and I had to close my daycare for two days last week because I could barely walk. I did not take anything other than tylenol and Advil, so I was able to still have my daughter here (my son is at school all day) because she is really quiet and easy...all I had to do was manage to feed her. However, if I had been taking T3's or any other strong pain killer, I would not have felt good about caring for her. My doctor prescribed a msucle relaxer for me, but it makes you drowsy, so I did not take it at all because I was worried that I could fall asleep. I hope you feel better soon!
