I have recently taken on a 10 month old DCG, and I have a similar screaming problem (and she seems to have the loudest scream in the world....lol )

I've put the screaming down to a small baby suffering from separation anxiety from the parents & adjustment to my d/c.

After reading this thread I think I am going to try Sunnydays technique (thank you).

I have noticed that Mondays are the worst...I'm guessing that its a result of the parents being over attentive to the daughter over the weekend (understandable when they've hardly seen them all week) & the baby having to adjust back into my routine.

I'm also going to put a timeframe on improvement, i.e.if after 4-6 weeks I don't see a change in behaviour and settling into the routine then I will have to terminate care. More out of concern for the baby and the well being of the other children in my care
