I'm planning to fly across the country (about 6 hours) with my 3.5 month old soon - and I'm feeling a little overwhelmed! I'm not planning on buying a seat for her - is gate checking your car seat better than renting one there? Is it worth bringing our stroller - the only one we have is the BOB which is big and I worry about it getting banged up. Worth it to purchase a smaller stroller? Or maybe just bring our ergo/k'tan? We are not planning to walk miles or anything - we are going for a wedding - but it will be hot there.

thanks!!
