Reflux/wind - sitting up after feeds

[KittyB52]

My bottle-fed 5.5 week old struggles with wind and has (I suspect) a touch of reflux, although GP said it's 'normal' and just recommended that I sit her up for 1.5 hours after each feed. We've been sitting her upright on our laps for a good half an hour after a feed, but if it needs to be so much longer, is there a good chair/support we could use? The head of her Moses basket is already propped up with books.

Thanks in advance.

Could you try her in a sling or bouncy chair?
