No, All the specialists say the same, start early. Doctors and other medical personell might tell you to wait, but they dont know anything about stuttering. The only reason an SLP might tell you to wait and see is because of lack of resources. For your daughter its best to start early🙂 My son just turned 3, and We've worked with an SLP for several months. We're doing the Palin programme with my son and we like it. It's a process and a lot of work on a daily basis, but it's mostly indirect, so our son doesn't notice.
