My sister is in the peace corps and found a cheap flight home (NJ) for 2 weeks next month. She hasn't met my daughter yet. We found a flight for $300 for me and my daughter to go up to NJ for a few days while she's there. My mom has a carseat and PNP. I need to figure out a stroller to use.

I have LO in an infant seat (B-Safe) in a Britax B-Agile stroller. I don't want to bring it on the trip, since it's so expensive and I hear stories of them getting banged up. But I don't think she'll be big enough for an umbrella stroller, will she?

Any suggestions on a portable, lightweight, affordable stroller that would be appropriate for a nearly 4 month old? (She'll be 16/17 weeks on our trip and will turn 4 months 4 days after we get back.) She is very tall (95th-98th%) for her age.
