So my LO use to be the perfect sleeper, 6-12 hours straight. Now the past 4 weeks she goes an hour to 4 hours, then she's up. Sometimes happy, sometimes fussy. But always hungry. I'm so exhausted tired isn't the word anymore. I need help and tips. Feel guilty last night when she was fussy and up for 2 hours, I yelled at her. 😞 lost my cool, for a minute. Anyone else hit a sleep deprivation wall???
