Fussy at night

Erin

My daughter is 4 weeks old.

She usually naps fine during the day (with some exceptions) but in the evening/night she becomes very fussy.

For the past week she has been up from 12-4am and just cries depite being fed and having a clean diapee :/ I don’t know what to do.

Anyone else had this problem?

Thanks in advance for your responses ❤️
