Frustrated with fam

Okay so a little backstory I’m 21. I’ve been with my boyfriend for almost a year and a half. All of my family lives in Illinois while I live in Pennsylvania which is a 12 hour drive at least, not including pee breaks. Well I’m pregnant now so I decided to come visit my fam in Illinois because I didn’t know when I would be able to make it back here especially after the baby comes. My brother and his girlfriend have been together for 8 years and they are also 8years older than me. So me being pregnant and so serious with someone is a bit of a shock to them I guess. Anyway all I said today was that I really didn’t know how soon I would make it back to Illinois to see the whole family because of the baby just because I didnt know how traveling on a plane with a baby would be and a 14 hr car ride with a baby sounds like it would be rough (I was just saying what I thought since this is my first baby idk if this is how it really is) but anyway they keep making me seem like I’m an idiot saying oh it will be so easy people do it all of the time and then they always try to tell me things about kids because they think they know everything just because they are older than me and it’s so frustrating because they don’t even have kids 😭 anyone have family like this
