5 year old with complex IV can't stay asleep

[Guest guest]

has anyone had experience with their child being able to fall asleep

at night but waking up after 6 hours and not going back asleep and

being tired and not functioning up to her abilities throughout the

day doesn't sound like a big deal but it is from 3:30am on lauren

lets out an attention scream about every 10 minutes so nobody else

gets sleep either. this sleep pattern has been going on for more

than 6 months and her doctors have few recommendations that have

thus far not been helpfull. we have tried melatonin and benadryl

i'm thinking about elavil suggestions and comments are very

welcome thank you lisa
