I have an 18 month old son. Every morning when I hear him wake up, I go into the room and say good morning! How are you! really enthusiastically, but he doesn’t even give me so much as a smile! Just immediately asks for one of his toys that has inevitably dropped on the floor overnight. I feel a bit sad that he doesn’t seem especially happy to see me at all. I’ve asked friends who say their babies give them a massive beaming smile when they go in the room. Is my son’s reaction normal?!
