Overtired

Try nap / bedtime earlier x
Let lots of light into the house in the day
Eventually they get the difference between night and day x

Witching hour is a real thing. Go outside during the day and allow her see the change in sun set. Warm bath too

My yoga ball was my best friend in these moments!
I’d pop her in the carrier, sit and gently bounce while making sure my heartrate & breathing were calm to regulate hers.
Once she was asleep I’d transfer to laying chest to chest with her and she’d often stir just enough to latch and then go into a deeper sleep

Around that age I was literally just feeding baby and putting him back to sleep.

My baby is 5 weeks today and for the last two weeks we’ve had her getting over tired and unable to settle. Some nights she’s cried for 5/6 hours straight and finally crashed at 3am. We’ve found waiting for her last feed until she’s telling us she’s hungry. We turn down all lights turn off all devices and close curtains. Then quite roughly rocking her to sleep holding her upright against our chest and sshhhhing in her ear quite loudly calms her right down and then she falls asleep in our arms. We’re also finding we have more luck with her staying asleep the longer we rock her for after she’s asleep
