Either the dad would have had exactly the same ecstatic reaction if it had been a girl, in which case what’s the fucking point?
Or he would not have, in which case he’s a schmuck.
I really do not get this gender reveal stuff. Just tell the people in your life who care.
Also, judging from this, it is not clear if the mum knew. If she did, did she really keep it secret from dad?
If she didn’t, who did and who gets to tell the performers and balloon providers what it is?
I really, really do not get it.
