It could also be a growth spurt & so she is needing more feeds & will settle againj in a few days...
Maybe try to get her to feed a bit longer & hopefully then she'll sleep a bit longer before next feed...
Also I didnt know it but Indah used to feed every 3-5 hours during the day but from 5pm, she'd feed every 1.5-2 hours til about 10pm, then she'd sleep alnight, apparently she was stocking up so she could sleep alnight!????

Good Luck, have faith that although its' tiring now, next week things will have changed again!!!
