Anyone else?

This is my 5th pregnancy after the first 2 resulting in beautiful healthy little girls and my last 2 ending in loss last year. Well we got the great news 3 weeks ago we are expecting again. I'm cautiously excited but my hubby is acting like nothing is different in our lives. I get that he doesn't want to get attached and then have to mourn the loss of a 3rd baby. Anyone else dealing with this after a loss?
