Venting 🙈

So my mil & I are very close! We live in different states but FaceTime almost everyday! I'm 29 weeks and have had my registry for months now.. She has yet to offer to buy anything or ask what we need. She knows I am a planner and have things done well in advance- the nursery has been finished since Mother's Day. I'll mention things to her like "still gotta get the ???? For baby" and she never says "oh I'll get that" nothing. It's starting to really get under my skin! I talked to my sister in law about it and she can't believe that her mom hasn't offered to get baby anything. Not even an outfit :( would you say something or chalk it up to hormones and move on? :/
