Sleep disorder in 6month old. It normal!

My 6month old baby always had sleep problems whenever asked from epds they said it's normal whereas from the beginning I had to carry her in arm even during the night because of reflux choking and intolerance issues now everything is ok but still she doesn't sleep sound and wakesup after every 5 minutes or so because of which I have to leave all work and sleep along side her otherwise she gets awake and hyperactive n cranky all the day. She sleeps at night just fine. Which means she is only sleeping 8hrs in total whole day rest of the day it's very difficult as she struggle to sleep peacefully. My relatives also said that at this age child should minimum sleep for 10hrs. she is gaining weight slowly as she is breastfed otherwise urine output and everything is fine. Is it normal
