please help im such a bad mother..sleep issues!!!

[1pj]

so DS is nearly 6 months and his sleep is terrible,i dont get it because from when he was about 7 weeks he slept really good then he hit about 3 months and from then on hes been terrible i mean TERRIBLE!!!Hes waking all night heres an example...i put him down at 7 and he wakes at 8.20.9.20.10.20..(every hour)till about 2pm then occasionally he will have a 3 hour sleep but then be up forthe day at say 5am.

I didnt mind for a while and made all the excuses in the book but now im exhausted,im running after DD whose 3tomorrow and is very active and i just need some sleep,i cant work out what the problem is,i am naughty and he has a dummy and he is still wrapped up(which is another MAJOR thing because he wont sleep unwrapt but yet he wiggles so much as if he wants to get out of it but then if i dont wrap him he will only sleep for say half an hour instead and start hitting his face and all the rest and knock his dummy out and then cry again)i dont know whether to try a no cry sleep solution and i know they all say take the dummy away but i just tried before and he screamed murder and i actually for the first time ever felt angry towards him

hes such a darling so im sooo guilty now and i feel for my DD too because shes got a grumpy mum all the time i know i was lucky with her sleeping through from 7 weeks and not having to do anytrhing but 3 hours a night is getting exhausting especially when im up and down all night i ant even lay in bed and rest,all i eat is bad stuff to keep going and yet the weight is falling off i feel im brain dead all the time and just want to cryand i know its from lack of sleep and going pretty much 21 hours constant!

Has anyone PLEASE i beg you for any sleep ideas(that dont involve screaming)and that i can try with DD around too as id ont want it to be too stressful on her if hes upset she gets upset.

Should i unwrap him?is he wanting to be unwrapt now?But how will he sleep with his arms waking him up and should i try get him to not have the dummy?it seems when i go in im popping the dummy in all the time,then DH says first you want him to have it now you wanna take it away(yes im mean)i just dont know what to do and ive paid for so many dam internet books and all they do is say to wrap them and basically let them cry..i just cant do it but i cant stand being angry that feeling towards him ive never had that before and was awful
