I need help. DD has recently turned 2 and she still isn't a good sleeper. I work full time and I am truly exhausted. Almost every day starts at 445. She goes to Nursery and will nap there for 1-2 hours. When she gets home she's totally exhausted, we manage to keep her awake until 7.30pm though. She settles well initially but will wake at least twice in the night. I resettle her each time as DH goes to work at 4am. Without fail she'll be wake by 4.45 (4.30 today)despite my best efforts she doesn't go back to sleep. I can see she's exhausted though, she's really grumpy, as am I! Any tips? She's our 3rd and the others weren't like this.
