What is the ruling on the party held during the seventh or eighth month of pregnancy, where gifts are presented to the parents of the newborn, and is it an imitation of the disbelievers?

The basic principle concerning customs is permissibility, unless they are a symbol of disbelievers and polytheists, or a religious text prohibits them. Thus, for actions that are not acts of worship, the default ruling is permissibility until evidence for prohibition is established. Therefore, if foods or customs are not associated with innovative celebrations or imitation of disbelievers, they are permissible.
