My sister lost her baby boy in February, and I just found out we're having a boy.

My sister gave birth to a beautiful baby boy in January 2019, but he had major health complications and passed away in February. 😭 It was awful, and I met him before he passed, and he was so precious. 💓 I was already pregnant, but didn't tell our family until recently because it was really traumatic and I know my sister and her husband are still completely heartbroken (understandibly!). 💔 I'm 20 weeks pregnant now, and we just found out that we're having a boy. I don't know what to do other than tell my sister that my son will always be the 2nd baby boy in our family, and we'll never forget her little boy. Any advice?
