Everytime we go to the car, he checks with me that his grandparents are coming along, at least one of them. He asked me once in a very concerned voice when Jairamen Thatha and Saathi Paati are going to their house and I assured him that it was not for a long time. I think they are already his preferred playmates over me, and while that is a lot of relief for me at this stage, I feel a twinge of jealousy too.
A couple of years ago in Singapore, when his grandparents were visiting us, he was happy to see them in the lift but grew skeptic when they followed him out of the lift to our house. He desparately tried to will them away by waving BYE to them as they entered the house, but to his dismay, they kept following.
We've come a long way!
