I had similar issues when my dd1 was small. I think we are in the same industry. I found a video call on my meal break helped. But it did take a few years for her to truly settle. It wasn't until I had set days and set shifts that truly settled - she then knew when Mummy would be home etc. But video calls def worked a little.

DD2 is lucky because i work set shifts and days so she has never experienced a rotating roster and the turmoil of that. She does usually have to wait until I collect her in the afternoon before she sees me because she is usually still asleep when I leave for work.
