I made tea and put in on the table in front of dh. DH is lying on the sofa with 2yo on his phone/watching telly.
DH sits up picks up tea and holds it - even though it is still too hot to drink. 2yo DS adjusts and lies back on DH and knocks tea.
DH jumps up shouting Fuck fuck fuck. I can tell he's about to shout at DS. I tell DH he should have been more responsible with his hot drink and should anticipate DS's moves. DH still thinks it's DS's fault for "jumping on" him.
This is not the first time this exact situation has happened. Who IBU?
