DS is now 9, as a baby he had silent reflux and hardly slept at all. He still fiends it really hard to relax and go to sleep, but usually stays asleep.
DD1 was a joy, the best baby in the world (sorry all) I really felt she was my reward for DS. From 3 months she slept 7-7 ebf, would have a feed at 7 then go back in her cot to play/sleep some more. I also used to check she was still live as I couldn't fathom a child going to bed at 7pm, fed at 7am but was still in bed at 1pm.
DD2 was somewhere between the two, until she came out of her cot about a year ago. I think she has spent 2 nights in her bed since then. Occasionally she will go down awake in my bed (never her own) but more often she will refuse to go to bed at all, or I'll spend 2 or 3 hours sending her back to bed. She is so tired she is miserable. Last week she fell asleep in her tea at nursery!
To make things worse I gave a blood disorder which means I don't carry oxygen well in my blood, getting really tired, snappy, confused etc as a result. I was only diagnosed as my tongue was doer for 4 months and wouldn't get better. I just assumed that falling asleep as soon as you sit on the sofa was normal for a working mum of 3.
Every 2 months I have an injection to correct the blood problem. 2 days ago I was trying to work out why I felt so rough, yes, injection needed a week ago!
I'm lucky as I function well on 4 hours sleep. The problem is I am such a light sleeper that I wake up at every noise. Even when the kids sleep in I don't.
I had 5 days away from the kids in October, I still woke early every day, but it was my body being ready to wake up.
