Surprises

So my husband went against my wishes and told his family about the pregnancy. I haven't told my family yet. We agreed that we would do some type of 50/50 raffle with evryone regarding sex and actual dob. But of course he told evryone were having a boy.

It's annoying and somehow I would've like to have some surprise for evryone but he has the loosest lips ever.

Any suggestions on anything cute I can do to still be some type of surprise for friends and fmaily?
