Mood during sleep regression

Irene

I think my little one is going thru the sleep regression but she is so happy during the day, is that normal? Is she suppose to be super fussy? Lol she went from sleeping thru the night to now we were up probably almost every hour-2 hours with her yet she Still wakes up for the day smiley and giggling. Any one else go thru the regression and only thing effected was night time sleep?
