Wondering if anyone has heard of Tweddle? I have called them and got very little information of the phone except they said 'people seem to think we're controlled crying but we're not', which raised alarms for me!

I am having a lot of trouble with DS (11mo in a week) naps -- nighttimes have been OK except now where he has a cold and is cutting 4 top teeth! I feed to sleep at night but I carry him to sleep for days (we do this in an Ergo carrier). Fine except he is heavy and also I need to have other people be able to put him to sleep...

My MCHN recc'd Tweddle as an idea but I was wondering if anyone had used it and what they thought? I am not a fan of controlled crying and I do know his tired signs.

Any thoughts/suggestions?

Thanks
