Am getting ready to fly with my 4 mos old by myself in 2 weeks. I have a boulevard and then a peg infant carrier (she screams bloody murder every time I put her in it so thinking it wouldn't be good fora plane ride). I bought her her own seat. The boulevard is so wide I worry about the plane seat since we are in puddle jumpers most of the way. Also it is heavy and I don't really want to mess the seat up with constant in and out of plane and cars during our short trip! I was wondering about getting another one for travel. I want something light and that will recline well in the plane (our flight is from 6p to11pso I pray she will sleep). What options do I have? Is the coccoro best or the scenera? There is a huge price difference, but I want to make sure she is safe as well as make it as easy as possible.
