As much as I hate to compare Oliver and Heidi, but the only way to describe Heidi is probably to compare the differences between them...Heidi can drink better and hence I got to sleep more = ) Yet Heidi likes to make little sounds when she is sleeping and even when she is contented. Her voice is sharp and she has higher pitch than Oliver (of course since Oliver is a boy and Heidi a girl). But Heidi can cry really loud and scream when her needs are not met. I think she will probably be the fierce one around the house.
