Feed during take off and landing to help pop ears. Bring lots of clothes and diapers many babies get diarrhea from the altitude. My niece blew through 5 outfits in one flight.
Yeah ive had a niece and nephew from different sides of the family fly at 3 months and did fine. Just bring extra necessary things, especially for if baby cries. I know before plane moves they get hot sometimes because the acs not fully on so maybe dress them light and bring extra clothes to add layers.
just make sure you have a pacifier so the baby had something to chew for the war popping...it should be pretty easy.as babies are content to just be held...diaper changes.might be tricky but as long as you don't overpack.quick will leave you exhausted from trying to carryit all it shouldn't be to bagI
