The witching hour

anyone else’s babies have a super fussy period at night? The last 5 nights my daughter has been super fussy and inconsolable from midnight to about 2-3am. Midnight on the dot. Me and my husband are going crazy! She was sleeping amazing the 3 nights prior (5-6hr stretches) but now she just cries, nurses, just can’t be soothed for that whole time period. Shes 5wks
