When someone calls you by a nickname or some kind of "proxy", it usually means the following meanings: First, it is friendly. For example, if someone is thin, his friends may call him "monkey, skinny monkey" and so on when greeting him. For another example, many salespeople now talk about customers and customers as "handsome guys, beautiful women" and so on ~~

Second, they praise them with derogatory remarks and emphasize them (attracting the attention of the other party). For example, if someone is sloppy or often says the wrong thing, then others may call him "what a clown!" " ~ in connection with the situation you mentioned, your leader called you "baby", which is probably the case. That is, deliberately not calling your name, but using "baby" instead, in order to attract your attention to this matter.
