What should i do about my almost 3 year olds sons feet?

My sons feet have been pointing inwards for awhile now...his pediatrician told me not to worry about it when he was 1 years old. So i didnt but then everyone was worried about it, as was i. So i took him to a foot doctor and they put made him special braces for his shoes. Nothing was changing...so i set up a appt. with a foot surgeon and they took a mri of his pelvic area. The x ray showed that its actually his hips that are making his legs point inwards. The surgeon acted like it was only one of his hips but both of his feet point inwards and his left is worse than his right, when the surgeon said it was his right hip that was messed up. I've been verry confused with this. Anyways..the surgeon told me to put him in physical therapy for 8 weeks, once a week. So i did. The physical therapist told me he WILL need surgery and physical therapy isnt going to work. The surgeon told me after physical therapy for 8 weeks, we could try casts, and then if that doesnt work than he will want to operate on him. So we have done physical therapy for 8 weeks and tomorrow we have another appt with the surgeon. I'm really wanting to figure out whats wrong, if he needs surgery i want to get it over with, even though im dreading it. I just wanted to know if anyone else has gone through something like this and what should i do? I'm just really confused and worried about everything. I dont know if i should 100% just go along with what the surgeon is saying. If anyone can help..please do!!!!
