Currently in the throes of the 4 month sleep regression. I think its been 3 weeks? So tired I can't remember!
In your experience - how did it end?
a) gradually got better over a few weeks
b)fairly suddenly - baby just 'got it' and started sleeping for 3/4/5 hrs again.
c) It never did and you had to sleep train at 6 months?
Just wondering what most peoples experience was, as it feels like no end in sight at the moment.
