A few months ago I was brave enough to take my toddler alone from Washington DC to Austin. me to attend SXSW and my toddler safely deposited with his aunt to play with his cousins. The journey was great, he entertained Ranajune in Baltimore who was - also flying to SWSW - before we boarded and then promptly fell asleep as the flight took off only to wake up in Austin. The return journey was the same.
Now that my skills at taking a toddler cross country have been proven I am now going to fly with him to India next week. We have a 8.5 hour flight to Amsterdam and then 5 hours layover and then another 8.5 hour flight from Amsterdam to Hyderabad.
Now for those of you who have made a similar trip with only one parent , what do you suggest. Any tips and advice is highly appreciated. Please leave a comment here !
