med’s 8year old girl with ADD | ADHD Information

Many thanks for reading my post 

One of our twin daughter’s, 8year old 9years this year,
has finally been diagnosed with ADD, not the hypo type. She has been in speech therapy since 3yrs old due to
Expressive language difficulties,  still behind her peers, age group. We took our daughter to a neuro/pych and he did lots of test's on our daughter and found she has ADD.I don't know how this hasn't been picked up before, anyway, she was then sent to a consultant pediatrician that deals in ADD ADHD and he also diagnosed her with ADD, both Dr's have told us she will catch up in time, our twins weren't premature, The Dr gave her concerta,  Our daughter has been on concerta 36mg now for 3months, it has made a difference, she is talking better, obviously the medication is helping her thinking, down is she can't get to sleep at night, did try a lower dose of Concerta first but didn't help much, the 36mg dose is what she needs, we give her melatonin to help her sleep at night, (natural medication for sleep), . What  other med’s  have other  parents found help with this type of ADD e.g. is Vyvanse better or Addrell, Strattra etc etc, I don't feel like yet she is on the best mediation for her needs.
Any advice help would be great. Fizzy
