Invited freinds over for dinner…?

This is sort of a two parter question. My husband and I have invited a couple over for dinner friday night. They have two little girls, ages 2 and 3 I think. Our son is 5.

First question. Is it ok to ask the kids if they would like to eat before the grown ups so they can play after (while we eat and visit after) ? I don’t want to sound like we are leaving them out in any way.

Second question. Both my friend and I are almost 6 months pregnant. My husband wants to make cajun steak tips (very spicey) is this ok to serve? If not what are some foods that would be alright? ( If the cajun is ok for us to eat, I would still like to know what food ARE NOT good for pregnant woman to eat)

Thanks in advance.
No, I never ate anything spicey when I was pregnant with my son 5 years ago. I’m not crazy about spicey things til my husband made this dish. It’s awesome.
