My little brother was my Sarbala when I got married. And we had loads of couple pictures without him as well. In fact he only stayed on stage until the Nikkah. Once that was done he ran off, because he was feeling uncomfortable with the turban, the Sherwani and the Khussas.
Yes you are. The rasm is, that at one point he sits on your lap and that’s when you give him a little gift. Doesn’t have to be too fancy.
