DS is a screamer / yeller and it started in February ........... and it's still going Usually it happens when he is tired, hungry, trying to get your attention, trying to tell you something - anytime really We have started making noises back to him in a similar tone but a much nicer pitch (one that doesn't cause industrial deafness) and then he starts to copy our noises and it makes for a much nicer communication. He loves the imitation and will happily copy the nicer noise we talk to him in. SImilar to Marydean speaking quietly
