Identify itself with

Does "The infant then identifies itself with these positive feelings" in the following text imply:

1. The infant then defines its identity by means of these positive feelings

or

The infant can also disown a bad part of the object, including aspects of itself, by means of ‘projection’ – the infant literally projects its negative feelings onto another object, thereby keeping the good part of the object safe or, if that is not possible, it projects its positive feelings onto another object to keep them safe from its own internal aggression. The infant then identifies itself with these positive feelings at a distance, a process Klein calls projective identification.
