My oldest spent most of his first year in a PICU (pediatric ICU) for severe complications after heart surgery and got addicted to a lot of drugs (he desperately needed them, but was still addicted).
One of them was Chloral Hydrate to sleep at night-- a very strong drug.
His neurologist told us there was some things we needed to consider once he was physically weaned off of the medication. (#'s 1 & 2 are from him, the rest are from me!)
1. She may be OVER tired. Does she nap? For how long? Does she get enough sleep at night? At this age it should be about 11 hours at night and a 1 hour nap (or 11.5-12 hours at night if no nap.)
2. This is the way you get a child back on a reasonable sleep schedule. It takes a week or so but REALLY WORKS!
Lets say your daughter is going to bed at 11pm every night and sleeping until 9 am.
Wake her up at 7:30 am until she starts going to sleep at 10 pm.
Then, Wake her up at 6 am until she starts going to bed at 9 pm
Then Wake her up at 5 am until she starts going to bed at 8 pm.
After that is consistent, stop waking her up, and let her get up on her own (probably like 6-6:30 am) while still going to bed at 8 pm.
3. Remember that she is still little, and she is not in control of herself right now. I totally get your frustration, trust me! (I flipped out yesterday after my 9 year old did this whiney-cry for hours-- he has a hard time calming down once he starts crying--- so I get it)
4. Be firm with her, but work out a plan TOGETHER! Make it seem like HER plan? "So, after you go to the potty and brush your teeth, then what?" Where does she WANT to sleep? My daughter (also 4) has been sleeping in a sherpa sleeping bag ON HER BED for 6 months because it is "cozy" and thats where she wants to sleep!
Sometimes she puts it on the floor and makes herself a little bed. Sometimes she goes to sleep in her chair in her room. I don't really care. She just needs to stay in her room--- at least at first. She still comes into our bed at about 2-4am every night. That is fine-- she is still little and is figuring it out. She spent the first 2 1/2 years co-sleeping and nursing, and is weaning herself out of our bed. There are times she goes a week without coming into bed with us at all. We know she is growing and still needs the comfort of mom and dad. (Some of my best memories are curling up with my Mom in her bed at night-- she was always warm and safe!)
5. If she won't stay in her room--- that is very challenging. We have tried different things-- putting up a baby gate, putting a doorknob lock thing on the inside of the door and shutting it (which she HATES), and what worked the most was making a stupid little sticker chart! She got a sticker for every night she stayed in bed and after a certain number (at first it was EVERY night she got a sticker, than every 3rd sticker, then every 7th, then 14th then nothing!) she got something small she really wanted. (For my daughter it was always Chap-Sticks!)
I have a friend whose kid was TOTALLY into money-- so they put 3 dimes on the kitchen counter--- everytime he got out of bed bugging them for a drink, potty, whining, etc, one of the dimes was taken. He got however many dimes were still there when he got up in the morning. (For getting up once, he got only 2 dimes--- if he stayed in bed the whole time, he got all 3)
6. Say prayers to try to figure out how do deal with THIS SPECIAL INDIVIDUAL CHILD. Heavenly Father knows her way better than even you do, and can guide you to deal with her personally. I have a very *fierce* daughter, and it has been a process for me (and still is!) to be able to deal with her--- she is just like me! GRRRR!
Best wishes, and keep us updated.
You are doing your best!
