Rose will probably frown, or look away from mary.

Explanation:

Generally infancy ranges from 0-1year. In this particular scenario,it is difficult to know  age of the Rose. This is necessary because, infants reacts and mimicked facial expression based on different age range.

Assuming Rose is up-to 2-months, she will just look away because infants at this age range can not copy or recognise facial expression.

However if Rose is 5 months, she can  recognise the mother facial expression. thus when her mother face was expressionless she should frown or fuss.
