Should I tell my family this....

I want to tell my family this but I also don’t want to hear their mouths. Im a very private person and I dont like ppl in my business no matter how big or small. I hardly ever personal stuff on SM and the only ppl that know im pregnant is my family.

Heres the thing

My cousin and his wife has caught a lot of flack since hes been married. All the way from how hes been acting since getting Married to naming his child Junior and him demanding ppl to dtap and flu shots to even see the baby.

Now i know my mouth and how I am so I feel like when i say this to my family they gonna have some 💩 to say and how im acting like my cousin and start talking 💩 about me

and thats gonna make me go off and cut them off.

My question is should I tell my family this even though I didnt do this with my other two kids who are 9&12?

Update: this wouldnt be said on SM like i said before im very private and hardly post personal stuff on SM. I want some of these DONTS followed.

I believe it is common sense but I have a lot of older ppl in my family that would and have done this.

It would be done in good taste.
