trouble falling sleep

I don't know why A has been had trouble falling asleep. last night she woke up crying. She went down to my room saying, "sorry to bother you and I know that tomorrow you need to drive a long way to work and u need sleep. But I just couldn't fall asleep. I woke up again and again and checked the time, 11pm, 1230am"
 My little Angle, u don't need to apologize to me. it is okay to ask your mom for help, any hep including sleeplessness. let's go upstair and tuck u in bed again. no pressure. just let me hold u in my arm till you reach your dream land safely.

This morning, A came over to my bedside told me she had s great sleep afterward and didn't know when she actually falls asleep and when I left.
Mom is away tonight. Wish you have a great sleep again.
