Crying at my 3D ultrasound

We lost twins at 16 weeks and then had a second set of twins at 25 weeks, only one of them made it home. We told our daughter that we were going to see her sissy today and she got really excited and said she was going to see Lainey (her twin), I started tearing up and had to tell her we were seeing her other sister, the one in mommy’s belly, she was less excited for that. I’m so grateful to still be pregnant at 30 weeks but everything always seems to be bitter sweet. Im just anxiously awaiting her arrival.
