So we are flying home to visit family in 2 weeks. I realized the airline we are taking says we can only take 2 of the 3 following items: pack and play, car seat, stroller. So... which one should I pick and what are some cheaper options to grab while I'm there? Car seat is a given.. we will be driving. but I'm looking for strollers at Walmart and not sure what he can really be in. He will be around 5 months at that time and a lot of cheap strollers are 6+ months. Buying another pack and play just seems ridiculous.
