I was knackered yesterday so my partner said I could have a nap and he'd look after our 13 month old. It turns out he spent 2 hours playing on his computer with our son playing by himself. Whenever our son got fed up he tended to him for a short while but otherwise he was playing on the computer.
My partner thinks it's OK because he stopped playing when our son needed him. Aibu to expect a little more effort when it comes to looking after our son? I feel like I can't leave them alone now as it seems he was a bit neglected...
