6 month sleep regression?

Ali

My Baby went through a ROUGH 4 month sleep regression and afterwards was sleeping through the whole night no feedings and I was able to put him down whilst awake for him to fall asleep. He would sleep til morning. Again now he is fighting sleep and waking at least once in the middle of the night inconsolable unless I nurse. Is there a 6 month sleep regression I wasn’t aware of? Did anyone else deal with this!
