Attentive mother in law

my mother in law found out I was pregnant And i feel like she’s been nicer to me and more attentive. She’s never been mean to me or anything but I always felt a wall from her maybe because we don’t know each other 100 percent since she just recently moved to the states. However since I’ve told her that vibe has changed, I feel closer to her. She got me maternity clothing and some baby stuff yesterday since it was my bday. I don’t know maybe I’m overreacting. Has anyone experienced this?
