This is our first child, so we're really not sure what to expect...
We will be attending a wedding this summer that requires an approximate 12 to 14 hour drive each way. While we recognize that the trip will take longer and will require frequent stops, is there anything else we should be concerned with? We won't have air conditioning, but hopefully we can work around that somehow...
We're also considering flying (which would be a less than 2-hour flight) but I'm concerned with all the things we'd have to drag with us - car seat and stroller mainly. We're planning to breastfeed so no worries about food.

Any insight anyone might have about how do-able this is would be appreciated.
While we recognize that we may not be able to make a final decision about whether or not we can go until we see how we/baby are doing, it'd be great to hear from other parents who have done it and how it went.

Thanks!
