When would be the best time to find out babies gender

Ca

So ladies I’m in a bit of a dilemma, so this is my second pregnancy but my husbands 1st and our appointment to find out the baby gender is March 12 but our anniversary is March 3 so I have this idea for me to go find out the babies gender by myself and as an anniversary gift have the gender reveal as one of his anniversary gifts but idk if it would be best that we both go find out he gender together since obviously it is a special moment

Ps: it’s be the gift they says sight and id obviously tel him to open it last
