If your child has stuttering for more than 2-3 months be sure to seek professional help (Psychologist / Speech Therapist). Children have a huge success rate in overcoming stuttering. Provided it is done at the "unconscious age" up to 5-6 years. And 6-9 years. Further it will be more difficult. So I recommend not to skimp on spending. Otherwise you and the child will only lose more from it.
