Sometimes they'll sleep more right before a growth spurt. One time my baby was sleeping every hour and then was very hungry and fussy for the next few days.. and then back to normal. But that usually doesn't go on for more than a day
How old is she if you don't mind me asking? We have just hit regression and curious as to how long it lasted for everyone's little ones. She was such a good sleeper from a month old sleeping from 19:30 until 7 in the morning. Now she's waking at 4am and restless from then until about 7 when I get her up. Xxx
Not sure if it’s normal but we are in the same boat!
I'd get her checked out, wake windows should never decrease
