Because for Christians, it was the day that Jesus took all their sin away, which is good, hence the name. It does still have to do with his death however, because through his death Christians have all their sins that they had once had and will commit taken from them. This doesn't mean that Christians will be perfect.

Friday
Maundy Thursday is the Christian holy day that commemorates the Last Supper of Jesus Christ with his disciples. It is significant in relation to Good Friday because it marks the beginning of the Easter Triduum, which includes the events leading up to Jesus' crucifixion and resurrection. On Maundy Thursday, Jesus instituted the sacrament of the Eucharist and washed his disciples' feet, emphasizing the themes of sacrifice, service, and love. This sets the stage for the events of Good Friday, when Jesus is crucified and dies for the sins of humanity.
No you certainly can not call your child Jesus in any way. First of all your child is a born sinner so he dies, . Jesus you see was absolutely sinless. That is the big difference. And I doubt if your child will die for anybody at all.
