I also have a special needs boy. He is 7 years old now. Perhaps, you may have read about my story in another thread. What i can say is dont't give up on them. GDD is developmental delay. At least, the comforting part is they are not life threatening. If my son can do it....i believe your boy can also acheive it. Your boy is now 3 years old and it will help him alot to persist with all the therapies. As long as he shows improvement, dont't lose hope...
Whatever the milestones that my son have acheived dont't come easy. He used to have a lot of therapies and all my annual leave are reserved only for him. I am a full time working mum, cannot afford to stop working as his therapies are all very costly. It will be very heartening to see that he cleared all the milestones to reach what he has acheived today. When we heard of his diagnosis , we have never imagined that we could one fine day, start him on mainstream and bring him to travel as his immune system is pretty weak. But, he cleared the hurdles and our family just returned from a long trip in Aussie during the June holidays. I told my hubby... is like a dream come true and whatever efforts that we have contributed in him have been rewarded. My boy still has more hurdles to cross..He still has heart issues and the recent visit to the cardiac specialist says that he may need to go for a heart opt next time if the regurgitation in his heart gets worse. I am worried as well but i tell myself that i will fight this battle with him if he really needs to go through the opt. He is under the learning support program in his primary school and with the coaching support at home and also thru his school teachers, he managed to pass all his papers so far. Primary school teachers are now more aware of special needs kids and MOE have also came up with this learning support program for kids who are academically slower. I find the program very useful for my boy as is a smaller group and he is not overly stressed with the faster teaching pace in class. I always set short terms goals for him and it motivates him and me as well, whenever he acheive those goals.
My son is diagnosed with di george syndrome, born with congenital club foot and has congenital heart problems.
