I have a just turned 2 yo dcb who really struggles with listening. E.g. ignores me when I call him, wanders off, difficulty following directions. He is mildly delayed language wise but this has improved since joining us. I only have him part time so I feel like I am always starting over with him. How much is this just 24 mos old boy stuff and how much can I attribute to being behavioural? I feel like he is more like an 18 mos old sometimes. Any tips?
