Hi I stutter and my son has a mild stutter with other speech disorders. A friend of mine who is also an SLP very experienced in stuttering advised me not to do... anything. Don't give attention to it, and interact with her like you normally would. Like others said, most kids grow out of it. If it continues to 6 months, maybe closer to a year and she is getting frustrated by it, you may want to seek out a SLP trained in stuttering. You may have to pay out of pocket because the typical "speech mills" dont have qualified SLPs.
