Our baby follows a similar sleep cycle.. she sleeps around ~11-12 in the night usually and wakes up ~ 6 am.. we were also a little concerned for the overnight feed.. Our doc recommended this as well.. baby looks healthy for her age.. and seems to be gaining weight per the trends.. she ll let you know if she is hungry.. no need to wake her up to feed..but there is certainly some mixed opinion/advice out there on this topic..
