11 month old starting to bark at people

Hi Everyone,

We adopted our now 11 month old lurcher/spaniel mix at 10 weeks old and all has been great. She has picked up training easily and been great on the lead and with people. However we recently found out we are expecting our first child and she has began to bark at people both in our house and when visiting family.

This has included instances where she would be cuddling and asleep on the lap of a family member who then left the room for a couple of minutes to be greeted with barking when they came back in.

She is very food driven so we have tried to have treats on hand when she is around someone who makes her bark and rewarding her attention on us or when she is quiet, but this does not seem to be helping.

She attends day care a couple of times a week and they haven't mentioned this behaviour either.

Would anyone have experienced similar? And have any advice? With a baby on the way we are anxious to make sure this behaviour doesn't escalate.
