Erin, sorry to hear things aren't going well, what if you try putting him in the pram/stroller and get one of the girls to push him around the house, I used to get Zoe to do that and he would fall asleep in there and I would just leave him.
Don't worry Will is doing the same, being very clingy to me during the day, always coming up to me crying, he is not normally a dummy boy either and I have been giving it to him during the day to keep him quiet, and his day sleep is now only 1 hour at the max, he just wakes up screaming and yawning but won't go back to sleep not even with his milk. I think he is getting some big teeth too.
Sorry Erin I'm not much help, that's all I can suggest.
How are you going with Jess, I know Zoe has been a real terror these past few weeks, she is just not listening at all and talking back, terrorising Will. I sure hope she grows out of it soon, she never really went throught the terrible twos so I guess she is making up for it now. She has even been in trouble at Kindy.
I hope Chris settles down soon, and you get some much needed sleep.
Feel free to chat to me if you need to..
