Doesn't cry

Erin

So my baby might be a little weird. She has never cried when she was uncomfortable. If she is cold or hot she just sits there. Same for if her diaper is full. I don't let her just be hot, cold, or stay in a dirty diaper. She just doesn't cry to let me know that she is uncomfortable. I thought she was just a chill baby but my mom seems to think she is weird. Any thoughts?
