So, our parents surprised us with a trip to Mexico! I'm so excited, but it's relatively soon, and there's a lot to figure out. We've flown internationally, but never with a toddler. Sadie will fly as a lap infant, but we'll be renting a car when we get there., so we'll definitely need a car seat for the week. We can either rent a car seat from the rental company for $4/day or we can bring and check our seat. Would it be a huge hassle to check our car seat? We don't have a case or anything, so I'm worried it might get messed up. Would you trust a rental car seat?
