Hearing aids

Recently my mother and I noticed a huge decline in my daughters hearing. She passed the hearing tests when she was born and in the hospital. But about a month ago no noise would bother her, so we took her in to get tested and one test after another yesterday we finally got real results. She has moderate-severe hearing loss in her right ear and severe in her left ear. So they have told us we need to start the process for hearing aids. I am really looking for advice from someone who has experienced this with their kid. Is there a type of hearing aid you found to work best?
