Fredi won't get much time to rest this week, though, with a trip to Southampton followed by Saturday's game against Blackburn Rovers.
Not that he is complaining, after his snapshot on the turn rescued the Hammers' cup dreams at Stamford Bridge at the weekend.
It completed a busy few days for Fredi, who says: "I have scored a goal for my son, Ibrahim, and for the team. It came near the end so it was a relief.
"I can sleep. He doesn't cry much so it's alright, but I don't know if he will be a footballer - he can do what he wants."
The celebration had echoes of the famous Bebeto reaction to scoring in the 1994 World Cup finals following the birth of his child, but he says: "I didn't think about that. Everybody does this when they have just had a baby and they score.
"I needed the goal as it was so hard the previous week. I wanted to score because it is always important for a striker, and I hope it will carry on.
"Last week it was very difficult for the forwards because Chelsea dominated us, but everybody worked hard on Saturday and it made it easier for us.
"I did believe we would equalise all through the game and I wanted to do something - it was a relief when we scored."
He nearly even grabbed the winner with a header past the advancing Cudicini, but the ball just span the wrong side of the post.
"I knew the goalkeeper was coming out of his box and I just closed my eyes," he says.
Unfortunately the celebration from the Hammers' 6,600 fans behind the goal wasn't forthcoming, but Fredi is sure the team can advance to the fifth round.
"I hope so. We have to believe so - or we might as well stop now," he says.
