I haven't been to Trisillain but I have definately thought about it. We were booked in to go- we should have done day stay today- but I pulled the plug a few weeks ago. I just can't stand bubs to cry and I don't think it's good for them. We are still not sleeping very well but i'm resigned to that by now- I figure that is the reason I'm at home and not working, so I can do the wake ups at night.
I just thought I'd throw in that I've heard Karitane is better than Tresillian as they are much more gentle and flexible and offer a lot of other options instead of just cc. From what I've heard, Karitane will allow you to be more flexible with your routine rather than just laying down one set routine for all babies.
Trish- just for curiousity, was the getting-kicked-out-for-co-sleeping thing because of SIDS recommendations? or just because they are aginst co-sleeping? Your post made me feel better about my desicion not to go Tresillian btw- not nice for you but nice to hear that Tehya is still a shocking sleeper even though she's been 'trained', I think Ty would be the same.
