Bragging Coworker

Hello, I have a question about a coworker that I perceive to be bragging and feel that the things she says are to boost her own ego. For example, she will say that her husband is so fit and has a six pack and then waits for me to say “that’s great.” Or her kids will win awards, or she is going away for the weekend and cooking their own food because they do not eat out and again I perceive that she waits for me to say “that’s great.” My problem is that I feel like I am always punching her ” your great card” and I don’t want to but awkwardly saying nothing after makes me look jealous. I would appreciate your help in seeing this in a more useful way so that I don’t feel annoyed as often at work. Thank you.
