4 month sleep regression

Hi Ladies!!

HELP!!

My little boy, who is now 18 weeks, is seriously suffering with SLEEP!!

I've read about 'sleep regression' but not sure how long it last, how to get through it or if it even exists!

He was a good sleeper! Woke every 4 - 6 hours for feeds but now we r up every hour and awake for a few hours each night!

Any tips of how to get past this or even how to survive the sleepless nights! I'm currently on my 17th night of 3 hours broken sleep!
