I’ve read about so many 4 month olds who sleep 7-7. My daughter is still up 1-2 hourly at night and has a late bedtime (she comes up with me)
I’ve tried and failed to get her into her bed early, including bringing her bed to the living room for the evenings, but she’ll literally only sleep in my arms 😴
She can also cry a lot during the night when transferred from my arms to her basket despite me keeping it warm 😕
