Yes you can by all means travel. Make sure to close ears of baby by small cotton, so that direct air won't rush inside your lil ones. Try not to use AC. .if so cover baby properly and AC vent should not be directed to baby. If u are feeding baby, they will sleep mostly when u travel. Any favourite toy ( rattle) you can carry. Keep its diaper, wipes, garbage bag to throw dirty ones all reachable.
