Eating less during the night??

yssej7

My DD is a month old,she's going through a growth spurt and eating almost every hour during the day and about every 2hrs at night(sometimes longer) But during the day she'll eat about 2.5-3oz and at night she just wakes up for a little snack of 1-1.5oz and she'll be dead asleep again.. She's gaining enough weight and everything.. Is this normal?
