4 month sleep regression

Chelsea

How long did it last for you? My daughter is 17 weeks today (4 months on Friday) and we’re starting the 3rd week of the regression. She’s up every 1.5 hours if not less sometimes. We’re struggling hard. It has not affected her naps though (although we both work full time so we don’t benefit from her sleep during the day 😩). Will this end soon??
