Need help baby sleeping thru night

My baby is starting to sleep thru the whole night since she was in 2nd month Now 3months She is still sleeping thruout the night from 10pm to the next day about 11am or 12pm for feeds Is this normal? I went to kk and they mention as long as per day her feed is ok and her weight is gaining it will be fine But I am still worried . Baby will wake up in the middle of the night kicking blankets but fall asleep back again Should I just try to feed her even thou she is sleeping ? I tried but she will be wide awake after feeding an I will take 1 hour to put her back to sleep again Any mummies facing this kinda issue ?
