Nassau,
I just did my first solo flight to LHR with my toddler whose almost 2, in diapers and survived. I wasn't looking forward to the changing onboard part on the flight, but its not too difficult as long as you're organized! Advise:
- Buy lots of large ziplock bags, a tub of wipes and a small fold up travel changing pad.
- I made up about 10 ziplock bags each containing a diaper and many wipes, then sealed each ziplock bag and put it in the diaper bag. Then pack a few loose diapers, a travel size case of wipes and toss it in the diaper bag.
- Change your kid just before boarding in a washroom. Most airport men's rooms have changing stations these days.
- Ask the Crew which lav has a changing table when you board. That makes things easier when you actually have to do the deed.
- When it's time to change the kid I found it helpful to discreetly leave his shirt on but take the pants off before heading back to the lav. Grab a ziplock bag and changing pad and head to the lav. Place your supplies on the sink console and take it from there. I found there was enough room in there to get the job done reasonably well (even a nasty diaper and a fidgety toddler). When you're finished put the used diaper and wipes in the ziplock bag, seal it up and throw it in the garbage bin. You'll survive...have a great flight!
