After cleft palate surgery, will my daughter speak properly?

Hi doctor,

My daughter is 2 years 10 days old now. She has been detected with a soft cleft palate when she was 1.6 years old. The surgeon asked us to wait for a few months as she needed to be more healthier than the current scenario at that time. Now, we consulted the surgeon again and he said that my daughter can get a surgery now. But, we also checked with a few other surgeons as a second opinion and they questioned us for delaying the operation. They informed us that it should be done normally by around 6 months of age. Are we really late for this surgery? As of now she speaks a few words, but it seems a few words are coming from her nose. Will she able to speak properly after surgery? Also, we are worried that whether she will speak or not. Is it too late for us to take her for surgery? Another surgeon has diagnosed her with a soft cleft palate and post hard palate. Will they handle both in same surgery? Please help us.

Thank you doctor,

Thank you very much for your time and valuable answer. I need clarification on below points as well. Will she able to speak properly after surgery? How many operation she need overall?
