Lately I feel that my wife is paying too much attention on our newborn. So much so that she doesn’t even say goodbye to me when I leave for work. How do I tell her that I feel neglected?

Its a new baby... so of course she's going to be paying attention to the child. Maybe plan a romantic evening, surprise her with flowers, or just buy her something nice like a new bag or jewellery. Its alla baout rekindling the romance! good luck bro!
