My baby is just over 13 weeks but I think we’re in the pits of the 4 month regression as sleep has been awwwwful for the past 2 weeks. Max 2 hours asleep at a time, long wake windows (1:30-3:30am last night) and not settling.
Did you experience the 4 month regression? How long did it last? Did you do anything that helped it come up an end or was it just a case of riding out the misery?
