4 month sleep regression

Lorena
My LO was a great  sleeper during the nights. We had his routine and he would sleep 7-8 hours. The past two days though has been awful. He guesses to fall asleep and sleeps for only 2 hours at a time.  I'm reading about sleep regression and how it's a healthy milestone, but was wondering how moms are dealing with this. Haven't slept in 2 days :/ need help.
