Finally got my BFP?? When to tell?

CONGRATULATIONS! We told everyone by ordering shirts for my 2 kids off the internet. My daughter's said, "If you think I am cute just wait till you see the new baby" and my sons said,"Oops they did it again, I am going to be a big brother". We went out to eat one night with the whole family and changed their shirts in the middle of dinner. What was funny is no one noticed so I had to tell my daughter to tell her grandma to read her shirt. Then her g-ma was like "ohhh cute" (she so didn't get it). Then my daughter walks away and my sister in law says "wait did you read that" Then they see my sons and everyone started clapping it was sooo cute. Anyways whatever you decide to do I am sure it will be perfect!
