Feeling so low

[calimommy]

This morning is the lowest I've felt in a long time. I have two lovely, albeit challenging at times (what children aren't?), children who just don't sleep. I feel like we have tried so many different solutions, nothing seems to work. They are nearly 4&2yrs old (in July) and I'm expecting again for early September. Usually I just brush it off and I've generally accepted that some children sleep and others don't. The older child was horrendous as an infant and improved greatly after 2/2.5. I was able to let him cry it out and he is v good for going to sleep. I can say goodnight and close the door. But the rest of the night was and is the problem. Even though he's better now he still wakes 1-2 times min and has a little temper, not night terror (he has them sometimes but that's fine) usually because his doadie is missing in the bed. I'd really like to get rid of the doadie, it's just night time now, because I feel like it's waking him, but he is dogged about it. And I'm a pretty strong willed person but I feel I'm loosing the battle there. Tips for getting rid of that are welcome.
Dc2 was a Velcro baby and still wants to be close, he wakes often as well, sometimes every 1-2hrs. He was and is never successful with cry it out, he gets far too upset and so I don't do it with him. He also has a doadie but it's loss doesn't seem to wake him, just the lack of companionship... I have recently moved them in to the same room, thinking that 1. They might be a comfort to each other and 2 if they wake they tend to wake each other even from different rooms so it's much easier to sooth them both at the same time. It was rocky at the start but we stuck with it and we seemed to be turning a sleep-corner. Now the last 1.5 weeks has been awful. I'm at breaking point and questioning everything again.
They have both slept through the night on occasion, sometimes 3-4 nights in a row both in the same room and separate rooms, so I know it is possible for them to sleep.
Not really sure what I'm looking for with this post, maybe just some similar stories? This morning I feel like throwing in the towel. Not sure if it's a good or bad thing that I can't just throw back a glass or two of wine and get on with it.
