I have twin boys who are 26mnths old, they were terrible sleepers, didn`t sleep through till 14mnths. It`s a long process but, I set a sleep routine that goes like this, bottle of milk whilst watching relaxing dvd, walk aroung the house holding bub, (hubby holds other)singing twinkle, twinkle little star, walk into bedroom, continue singing, have turn cuddling each bub, lay in cot ( continue singing), walk out of room. Most nights they self settle and go to sleep all night. First couple of nights they will kick up a fuss, I stayed with them, held hands through cot bars and kept on singing, I felt that they were alot calmer with me there, they still cried but were never hysterical, i always picked them up if they cried too much, some nights in got to the stage, that they were asleep, and I couldn`t get twinkle twinkle little star outta my head, don`t think I ever will. I`ll be an old lady rocking myself to twinkle twinkle little star in a padded cell LOL !!. I suppose what I learn`t from this is to be consistant, it`s hard work, but if you do exactley the same things say the same words, sing the same song, they soon get it. Well it worked for me after alot of hard work, I think some nights I cried more than them. I still do all of this and they are over 2yrs old, Hubby thinks I`ll be doing the same sleep routine when they are 21. Too sacred to chang what works, sleep depivation is still a very harsh memory. Hope this makes sense. Best of luck.
