I went to Twedle earlier this year, and if they say they dont do controlled crying, they are lying! Thats exactly what it was!

I was told to put DD down in the cot wide awake, and walk out of the room. When she started crying, I could go in there, and pat her and make sshhh noises till she calmed down, but couldnt pick her up or look her in the eye. When she calmed down, I was told to walk out of the room (this took about 30 mins), and then if she started crying again, wait a few more minutes, and repeat the process. If this isnt controlled crying, I don't know what is!

I would definitely look into the other schools, cause I dont think Tweddle will give you what u are looking for. Let us know how you go!
