Hi Kim-- I have 2 year old twin boys. I was in your shoes not long ago. My boys were not great sleepers by any means. Try feeding them every 2-3 hours during the day. The ped dr recommended that to me and it helped. What helped me the most was Healthy Sleep Habits Happy Child-- the book. It is really rigid but I'm telling you it saved my life. I was at the end of my rope with their no sleeping and then my no sleeping. Get committed to it & you will have some sanity in a few weeks. I promise. You will hear from a lot of moms with one kid at a time thst the cry it out thing and schedule thing isn't what you need to do..... they cannot possibly understand your situation with multiples. You have to take control of the situation (as much as possible) or the babies will control you. They will be much better off with a happy mother and a schedule (even if they have to cry it out to get there) then they will be with a frazzled mother.
Feel free to email me if you want to talk more. I know what you are going through.
