Christy, Sorry if you already know this, Try leaving Jovie for 10 minutes or so after feeding her before trying to burp her. She may need a bit of time to get it together to bring up IFYKWIM.
I only Burp Isla if she seems to need it, not each & every feed. Also it doesn't have to be a burp that happens, it could be a silent fart.

Oh I forgot, DH was asking me where you got the name Jovie from. I didn't actually know so thought I would ask.
