I am the crazy one taking a 10 hour flight on my own with my 9 month old. I am definitely going to need both hands at all times to get us and all our gear on the plane. I am checking the stroller so need a carrier for getting to the gate and going through immigration, etc. I am a large-ish lady (size 18) and looking for something sturdy and comfortable. I have a Moby wrap but would prefer an actual carrier for this occasion, not a wrap or sling, etc. Any suggestions?
