My daughter is 6 years old and in 1st grade. She was having similar problems in kindergarten and I wondered about ADD/ADHD but she's a very social little girl so I wanted to wait until she was in 1st and see if the issues continued. The issues did continue into 1st grade.
I went to her pedi and he said he is not qualified to make that diagnosis...it could also be depression, anxiety, etc. He gave me a list of trusted psychologists and I set up an appointment with one in our area. I had to fill out a ream of paper (at least that's how it seemed!), her teacher had to fill out a ton of paperwork and my daughter was tested. Through the testing, the Dr did say that my daughter is DEFINITELY ADHD...textbook case, as she put it. She discussed with me my options. I then went back to my pedi with the report and again discussed the options.
I know many people do not like meds for this situation, but for my daughter it has made all the difference in the world. She started her meds and within 1 month she went up 4 reading levels. She can focus and get her work done every day. She can participate in group discussions. She's a different girl.
One thing to know about the meds is that if they don't work or turn your child into a zombie, they are the wrong meds or the wrong dosage. OR your child has been misdiagnosed. Often times a child can be "co-morbid" (a term used by my pedi) where they have ADHD and another disorder. It's tricky to get the right meds. A diet change for my daughter did nothing...the meds were the answer.
How could I not get my daughter diagnosed and treated? How could I deny what she was going through? It would have never gotten better and her life would have been horrible! Because she has ADHD does NOT make me a bad parent! I think too many parents feel like it does.
I hope you can find the answer/treatment that works best for your family and daughter! Good luck!
