This time will pass and eventually you will look back on it and wonder if it was really true! My ds was an appalling sleeper, so bad that I resorted to keeping a diary to show doctor, health visitor, nurse, anyone who cared to look actually. If I look back on them now he is 15 I wonder how I ever survived. ..
I also remember getting very cross with poor cat who dared to miaow just as I sat down!
It certainly would be worth thinking about changing to formula if only to give you a break as dh could do some feeds and give you a break. You have done well to feed him for his first 6 months.
When DS was tiny and not sleeping, I would manage the night and then dh would take him early in the morning so I could sleep. We had a vibrating bouncer that DS liked and when he had enough of that, dh would take him out in his pram so if he cried I wouldn’t be disturbed.
May be worth speaking to a sleep clinic, we used Millpond, as they may have ideas that you haven’t thought of or different routines. Has been assessed as fit by gp? Our DS actually had a breathing problem which wasn’t diagnosed, or even though of, until he was 18 months. It didn’t make him sleep any better but helped me deal with the situation.
As I said DS is 15 now and sleep is still fairly erratic with very early mornings, but he doesn’t need me to be up with him anymore so all is good 😊.
Hang on in there, it will pass.
