Oh Layla I am so sorry you feel so bad at the moment, I don't know what to say I wish I could give you a hug. I think it probably is a combination of the time change and the SA causing her sleep problems. I think I read elsewhere your clocks have gone back? When ours went back in October dd's sleep went bonkers and I felt like it took weeks to get back on track. She was waking at 5 every day and at 11 months old it coincided with the start of this transition and having to cut her naps. I would go to bed at night dreading waking up the next morning - I would wake when dd did, look at the clock and just lay there and cry, as it said 4.45am or 5am. Also we have just had 2 months of full blown SA although I was really lucky as it didn't affect her sleep that much, but during her A times, boy was it hard going. Just like you I wanted to leave at times. All I did to get through it was keep telling myself it's not her fault, she's not doing it on purpose, she needs me, I have to be strong. I forgot about housework and cooking etc for the whole time and just spent
all my time with her- I even took her to the toilet with me. It worked- now she is miles better and will let me leave the room again.
Maybe try stretching her first A time more gently, say 15 mins at a time. Or keep her up but try something different- if I want to keep dd up a bit longer without getting overtired I take her out in the pushchair.
You are doing a fab job, try not to be so hard on yourself. I know it's difficult, we are all our own biggest critics. Sorry I can't give more practical advice but remember it's just another phase and it
will pass eventually, they always do. It just feels like forever when you're in the middle of it.
I have to go as if I don't wake dd now she won't go down again this afternoon
Post back or pm me to let me know how you are and I will get on again a bit later xxxx
