Our first child had no problems speaking quite clearly. However, our second child who is 2 years old has trouble pronouncing sounds like "vee" and "fee". For example, "vessel" becomes "bessel" and "Sophia" becomes "So-bee-ia". Will this problem naturally correct itself as she grows older?
We know a friend who had a 4-year old who needed speech therapy, though I do not know why he needed it and whether it was helpful. How do we know if speech therapy is helpful or necessary?
