She's up from 12am onwards. Wakes my eldest 4 year old daughter. Doesn't settle in my bed. Just wide awake all night. We live in a small 2 bed and 4 year old daughter has her own room and we have the other with our 19 month old. Thought we'd be able to let them share but we can't as 19 month old won't sleep! Sound carries also so my 4 year old is being woken up and she's due to start school in September. My partner sleeps on the sofa now. He works in construction so can have a serious accident on a roof if sleep deprived. That means I'm left to do everything at night and work part time on top which feels like hell. My days are merging into one another. I'm doing crap at everything because I'm so fucking tired. I don't know how to fix this. She has a nap of around 1 hour and a half about 3 hours after waking up in the morning.
