How to tell in-laws we’re expecting?

This is my second pregnancy, & they were very excited about the first. I’m afraid they won’t be excited about this one though. My son is 7 months old today, & I’m 10 weeks & 3 days. I just feel like we’re gonna get a lecture about how it’s too soon & all that. 🙄 But anyway, so far we haven’t spilled the beans, & I’d like to surprise them in a cute way. With my son, my husband just blurted it out over dinner. 😂 I’m trying to wait until we know the gender, but who knows if we’ll make it that far? We did a gender reveal cake for my son, so I’m trying to steer clear of that idea. We’re announcing to the world on the 4th of July. “Red white & due” or something to that effect. My son will also definitely be included in the announcement, because he’s gonna be a big brother. 😊❤️
