@jesusiscomingbacksoon I fly back and forth between Canada and US. My 32 weeker has done 3 round trips between 4.5 months and 10 months.
It was actually a weekend trip to Vegas (driving), where he caught covid at 4 months.
Bring your usual medication. I am not familiar with whst they have over the counter there so avoid the headache and know what works for your baby.
Bring snacks and various toys for the plane. For us, all rules go out the window on the plane. You want to watch h TV and eat stars for the umpteenth time - go for it little buddy!
I have a small stroller that I use to travel. Lots of people infant wear but they are not allowed at certain points in the flight. My guy also has a melt down in carriers.
I was able to travel with 2 items for baby (travels as a lap infant). I used it for a stroller and car seat. We have a fancy car seat at home but we use a simple lightweight one for travel.
I fly with soo much formula. I keep 24 hours in my bag plus a few extra meals as he tends to eat more on flight days. I also can't get his formula in Canada so I don't want to deal with trying to find what he's compatible with. Diapers, I usually have a few days worth but I pick up when I'm there so I don't loose valuable suitcase space!
