4 Month Old Pup Aggressive And Jealous Toward Older Dogs

We just got a four month old female Aussie two days ago. She has done beautifully with our two young children and is learning commands very quickly. The only problem that we have had is she is very jealous when I hold, pet, talk to my older dog who is 4 year old Shih Tzu. The Shih Tzu shows no aggression at all and even acts a little scared. I have firmly told her no many times but she keeps doing it.

I then brought her to mothers house to meet her dog, a Bernese mountain dog that wouldn't hurt a fly. The puppy growled at the Bernie and even tried to nip its face twice!

Is this something that will get worse or better with time? We have her signed up for puppy class but that doesn't start for another two weeks.

My biggest concern is that I am expecting a baby in 5 months and am wondering if she will be jealous of the baby as well? If this is her gene's talking I would like to know now instead of getting further attached and it not work.
