3 month old suddenly not sleeping?!

Amanda

My daughter slept great almost right from the start. 2 weeks old and sleeping 3 to 3.5 hour stretches and it just got better. For most of month two she would go down and sleep for 6-9 hours straight with no waking up. Now for the past two weeks she wakes up much more frequently and it’s just getting worse. Last night she went down at 7 and woke at 10,12,3,5,6:30. I pause and don’t rush right to her. If she isn’t full on crying and just kind of fussy I’ll let her go about 10 minutes and she usually settles back down. I just don’t understand why she’s waking so much all of a sudden. We were only doing one feeding throughout the night and I usually had to wake her up for it. Any thoughts?
