I traveled with ember when she was 1 1/2 months old. She slept through the flight and was a great baby to travel with. The problem I had was at check point. Instead of bring a stroller, I brought the snuggle baby pack. I wanted her close because I was traveling alone.
I just carried a diaper bag for carry on and checked in everything else.
The security gate made me take her out of the snuggle pack and place her in the bin. I had to remove the snuggle pack from my body and they ran it through the Xray along with the diaper bag. I had to give up the safety pins and babyspoon.
I had to unwrap her from her blankets and walk through the check point. I had to place her back in the gray bin because we set off the alarm.
I had to remove my shoes. It was the metal in my boots.
I put everything back together with no help~!! It was tough... SO the flight back I just carried her through check points...She was so small and snuggly anyhow...
I did feed her on take offs or she sucked on her pacifier to help with the ears. If you are going by yourself pack only what you need on board~ Less is best traveling with baby. You will have more time to tend to baby rather than baggage. And don't wear heal shoes or boots they will set off the alarms...
Have a safe and happy trip with your baby~!
