Actually there is a valid psychological reason for why she may be smiling at you when you look at her.

Attachment is enforced by eye contact and smiling. She is replicating what a mother does with an infant. Eye contact and smiling presents a warm, positive, holding space and connection. No words needed. It strengthens attachment.

See your response -- you said "you smile back." That's a connection.


Maybe she also really likes you and glad you are sharing with her.
