DS is three and has routinely woken up every two hours. Sometimes we can soothe back to sleep with milk, so on a good night dh and I take turns to do this from when we go to bed until about five in the morning. To me, that's like the very newest of newborn stage and it gets better for most people, but we have have done this for three years.
Bad nights one of us has to get up for two-four hours when everyone else is asleep in the early hours.
Very bad nights mean that ds doesn't even go to sleep until ten so we have no evening respite and then he does his being wide awake at night / early rising and doesn't nap in the daytime at all any more.
I'm used to it now, it's the way he is, but for the first year when you are expecting that one day it will happen, it was so depressing. Even in the second year of ds' life I still harboured hope which was dashed time and time again.
At the start of his third year I remember wishing for a minor car accident to happen to me. That sounds very wicked I know, but I just wanted to sleep for maybe one day or two no matter what pain or impairments I may have suffered.
Then I graduated to thoughts of more severe injuries and actually thought that they would be well worth suffering even if they turned out to be permanent.
That's how shite it is. I actually thought how welcome a stroke would be for example.
I got over it because I have absolutely no hope any more and so I survive. It has put paid to any plans of having another child before I am forty but there you go. Ds is loveable enough for two anyway.
