4 month sleep regression help!

CruzaB

What was it like for you? I’m trying to work out if my baby is in the middle of it or coming up to it. She’s 4 months now (3.5 corrected) and for the past 3 weeks has gone from having one long 6-8 hour stretch of sleep followed by another 2-4 hours to now waking after 3-4 hours then waking 1-3 hourly after that. Does this mean it’s already started? Or god forbid does it get worse and she won’t do the 3-4 hour stretch soon?? Looking for some hope!
