Have you experimented with putting her down after 30 mins, 10 mins, 5 mins etc?
I wonder if it's the time since the feed or just that after lying down for a bit, some wind accumulates and it wouldn't matter how long you winded for, it would still happen if that makes sense?
I guess it could be something else entirely non wind related! Like they just want a cuddle :)
Sometimes I needed to wind, lie them down for a bit and then wind again. From my Mum friends, there were a variety of winding techniques that worked for different babies. Over shoulder, flat over lap lying on belly, sitting on leg sideways patting, sitting on leg sideways doing a weeble impression with them (so you tilt them forward and then sideways then back, moving in a circle but keep a good grip!), standing holding them with your arm under the length of their body and rocking them backwards and forwards (pressure on tum and movement). Google for all the above.
Also you could try putting baby in a sling to keep them upright for longer. Or tilt the surface they are lying on - either with one of those foam wedges that goes under the mattress or by putting something under the top end of their bed stand/cot.
Sometimes the problem was more the bum end rather than tummy. If they do lots of drawing their legs up it could be because of this. In which case heaps of bicycles and leg movements generally can help, as well as tummy massage. Also holding them up under the arms so their legs dangle down straight. Theres another positon called the chair. Again Have a Google as there's lots of videos out there.
Some babies are windier than others.but most babies get this problem less from around 3 months. So it does get easier.
Gripe water is not advised for small babies. Infacol supposedly works by making all the small bits of gas into bigger bubbles so it's easier for baby to bring it up. We used it for a bit. It did seem to make more burps and eased things during a period of what appeared to be trapped wind pain that was quite extreme and I was desperate. The downside was that it also made a lot more sick. Also you apparently have to give it a few doses to work (not sure if that's true?) Plus you have to do it with every single feed and pipetting liquid into your baby's mouth isn't the nicest thing for them. I've been told by some bf professionals that the evidence base for infacol is pretty non existent but I've not researched it myself.
