Another drink?

At a birthday party recently I had the following conversation with someone.

THEM: What are you drinking?
ME: Flavoured mineral water.
THEM: So do you think you'll have another?
ME: Err.. yeah I guess so.
THEM: So you're enjoying it then?
ME: Err.. yes
THEM: When do you think you'll have another?
ME: I dunno?
THEM: Yeah I guess Maya is still very young.

At which point it dawned on me.  They had switched the conversation from my drink to babies.  As in "So do you think you'll have another baby?", "So you're enjoying motherhood?" and "When do you think you'll have another baby?"

I thought it was odd to be so interested in what I was drinking.
