HELP HELP HELP BEFORE I LOOSE IT!!!

[Nemo2007]

So my DC have never been the best sleepers but lately it has been getting ridiculous. DS is 3.10yrs, DD1 is 20mths and then DD2 is 7mths but I expect her to be a bit unsettled.
However a typical break down of a night follows here
7.30pm bed time DS usually asleep within 25mins, DD1 anything from instantly to 10pm
Around 10.30pm either or both will wake up crying. Back to sleep in 10mins,
midnight all three will wake each other resulting in then an hour or so of them being wide awake and alternately crying/playing/shouting etc.
3am dd2 will wake but it is less than 5mins to have some milk then back asleep
DS will wake various points in the night screaming
DS and DD1 will both be in our bed by 5.30am and ready for a full day by 6am.
Now DS doesnt sleep in the day, dd1 will have 40mins.
Their behaviour in the day is a nightmare, particularly DS.

Have tried
rapid return,
ignoring
rewards
punishments

All the above I have tried for at least a month at a time and nothing has worked. So I am now laying myself at the mercy of MN before I completely loose the plot as I am exhausted to the point of crying, I loose my temper and shout due to lack of sleep as I must only be getting 2-3hrs a night. DH is oblivious to half the goings on as he really doesnt hear them, he wishes he did!! Last night he didnt go to bed to try and help with them but it doesnt matter.

Nemo, I'm sorry, but I don't have any sage advice. I only have one so couldn't comment on the dynamics of three but just wanted to offer you my sympathy and hope that someone with some idea of what they are talking about, comes along soon.....

thanks beansprout

Do you use the same tactics for each child every time you try them? Would they respond better to different things?
Sorry - also have no real advice but BUCKETS of sympathy...

You could alwasy book into a hotel for a week and leave DH to deal with it

scooter I have tried using different tactics and using the same so Ds cant say I treat him differently etc etc

Nemo, as a first time mum of one non sleeper there is nothing I could tell you that you don't already know. Just wanted to sympathise and say what an incredible woman you are to still be sane after that. I really hope you get some respite soon.

Have you asked your health visitor or doctor if there's anything they can do?

sorrys cooter didnt see your reply.
I havent spoken to hv or gp as they will probably suggest phenegan. I am not keen to go down the meds route, however after DD2 waking last night at 9pm and not going back to sleep until 12.35am I was sobbing in the end. I am jus tphysically drained and I dont know what to do anymore. The only plus has been the past 2 days ds daytime behaviour has improved slightly as I have brought time out and reward chart back with a vengance. On the reward chart is a bit about sleeping but so far he hasnt achieved it!
