I just want to say there is hope for all out there..
my son is 11 weeks old when he was born for 2 wks he slept 95 ./ of the time after that he woke 5-6 times a night . He suffered server jaundice and we found out 3 wks ago he was lactose intolerant. He is my 5th baby and serfice to say if he was my 1st he would of been an only child.. my 4 girls slept through from 5 wks! He is not a content baby , has one doze in the day for 2 hrs( which I have a cheeky doze 😂) anyway I'm writing this to say there is hope for you all out there!!! My little one for 5 days now has gone down at 8:30 pm then wakes at 4am straight back down then up at 7am I think that's as good as it's gonna get! HE weighs 15lb and is 11 wks today, he is a big boy!!! Good luck
