Speaking on Radio Catalunya’s Tot Costa programme, Messi confirmed that with his eldest son Thiago, five, getting more involved with football he has had to take a new mental approach.
Messi also admitted that Thiago is getting to grips with knowing that there are some things that should not be discussed following a defeat.
'Since Thiago's birth I try to take defeats in a different way. But it's difficult. I suffer a lot and I find it hard to pick myself up again,' Messi said.
'It takes me a few days. And Thiago understands it. He has started to really like football and he follows Argentina and Barcelona and after a big defeat he doesn't talk about it.
'He knows it's best not to talk about it but sometimes he lets something drop and then he says: "ah I know we aren't talking about that".'
Although Messi is not part of Argentina's squad, he has not confirmed an international retirement.
However, the 31-year-old has admitted to opening up about retirement from the game stating he has shared the discussion with team-mates of a similar age.
'I don't know what will happen after I have retired. When the time comes I'm sure something will appear at the time. We talk about it sometimes with players who have a similar age.'
