How to tell?

Ya'll I found out almost 2 weeks ago that surprise baby #5 is on the way (my 4th, hubby has a son from a previous marriage) I have 2 cousins who are both struggling with fertility one of which had to get a D&C when my last baby was a few days old (he turns 2 tomorrow) and they still haven't been able to have a baby.. the other cousin was TTC when we were trying for our last and we were so excited to be pregnant together which again he's 2 tomorrow and she hasn't had a baby yet either.. I am so sad I have to announce yet another baby when my two cousins haven't gotten their babies.. I am grateful for this baby, I just don't want to tell them.. I don't want to be the reason of more saddness or reminders of what they are trying so hard for. It's not fair. 💔💔
