My wonder weeks app says my 13 week old is in her 4th leap. This can go on for another 30 or so days. I’m wondering if the 4th leap is the same as the 4 month sleep regression?

My daughter has been falling into her own night time routine the last few weeks, down anywhere from 8-930 then up at 445(if at all!) then up around 7 or 8, and I have been LIVING for it! This past week my husband and I have noticed she is beyond restless. I mean constantly throwing her legs up, moving, stirring, making noises. We keep checking on her but her eyes are still closed. Just beyond restless.... she’s also been fussy more during the day. Not in pain or anything just extra whiny 😫 I’ve looked it up and it seems as though the 4th leap and the regression coincide. It says the 4 month sleep regression typically happens in babies between 3-5 months of age. Are any of you moms going through anything similar?
