To try or not to try (baby edition)

Okay so I have major baby fever but like at the same time I don’t well mainly because I’ve been thinking about how a new baby will change up things and I just feel like when I first got the idea of “hey let’s make another baby” I wasn’t being realistic with my self. I need some advice ladies anyone have a 2 yr old and a newborn? How’d you adjust to the new lifestyle? Is there anything you wish you knew about before ttc? Please tell me everything 🙏
