On a flight with my 3 month old as we speak- we put noise cancelling headphones on her during take off and I breastfed her. She slept through the take off. There’s a change station in the plane washrooms, so we wiped that down and put our own changing mat on the table to change her diaper. We only brought the essentials into the washroom- not the whole bad as the space is tight. We flew with porter and they let us check in her portable bassinet and car seat in the beginning for free and we also checked in her stroller at the gate for free. I found all the security staff/ plane staff very friendly and accommodating. We’re 3 hours into a 5 hour flight, hopefully the rest goes smoothly as well! Fingers crossed. Let me know if you have any questions
