@irisalert,
That is an old wives tale. Why ask your mother - you would be better off asking your child's doctor. And don't believe Oliver - babies are easy to travel with - unless you have an extremely fussy baby.
I traveled across country with my infant when she was only about 5 or 6 weeks old. I asked my daughter's pediatrician. She said this is the best age to travel - at that age babies sleep most of the time and are easier to travel with. As long as your baby is healthy there is no reason not to travel with her.
She was born on Nov 13 and we traveled a week or so before Christmas went to Montana for a week and then hopped another plane to Seattle for a week and then traveled back to the east coast.
On the first flight as we were getting off the plane carrying are little one, people remarked wow I didn't even know there was a baby on board -- she was so quiet. What a wonderful baby.
Much easier to travel with --- much easier than a toddler.
Now the only hesitation I see is you state village - so I am not sure where you live --- not sure if there is a difference in travel, weather, illnesses that easily spread, or anything else as in safety issues? If not whether you drive or fly babies typically are lulled easily to sleep with the movement of the car, train or plane so even with fussy babies at that age they usually sleep during travel.
