Can apply ruyi oil. Drop 2 to 3 drops onto your palm and rub both your palms together very quickly. Then place one of your palm onto baby's tummy for about 5 secs to transfer the heat onto her tummy. Rub palms again and do the same for about 3 or 4 times. Do NOT rub or apply the oil directly onto baby's tummy. You can also do the same for her lower back and soles of her feet too.
Have you tried swaddling her? Some babies sleep better when swaddled.
