Mt boyfriends family doesn't know I am pregnant: Advice?

How would you Mama’s feel? About a secret that your son/daughter kept from you. About them having a baby. And they’ve kept that secret for 5/6 months? So all my family knows about my pregnancy. But my boyfriend’s family doesn’t. He’s kinda scared to tell them. (Mind you were 23/25.) We each have a son from previous relationships. His is 3. Mine is 4. But I mean, I’m kinda hurt that his family doesn’t know about ours. I get they only know he has one son. But I mean, I get it shocking news. But it’s like getting to the point where time is going by quickly and I’ll be home with a baby. And when they come to visit. And see a baby???
