Perhaps. Its just a nagging feeling ..... guilt on my part I suppose. My two oldest have been assessed as gifted, whilst I don't think the third will be. I had all three children within 4 years, and simply know that I gave much more time and attention to the older ones in their early years, than I have the third. Please don't get me wrong, I'm not worried about her development (she is easily on par with her peers), and I believe she is equally wonderful and talented - just not in the academic field to the same extent. Surely one-on one input (which is in shorter supply with multiple children - actually almost non-existent for a third), is going to have some impact. Agreed each family is unique - in fact DS2 scored higher than DS1, but the nagging feeling continues .....
