So it was Eva's first flight and I was really nervous but followed all the instructions received from BabyChakras beautiful moms. Here's few tips that has helped me in a safe,calm and comfortable flight.
1. Pack a handbag with the essential things like diapers, wetwipes, baby lotion ,extra pair of dress etc. (I kept only my id, lipbalm and phone&charger in that bag for myself).

2. Make baby wear a comfortable bodysuit and cap so that baby is cosy.

3. Reach the airport well ahead of time so that you have enough time for dropping baggage and security check-in.

4. Change the diaper once before boarding the flight.

5. Feed the baby while taking off.

6. Keep some cotton in both the ears.

7. Keep some toys to entertain the baby if he/she cries in between.(I kept a soft rattle).
One thing I did was keeping the partition handle between the seats up as it gave us more space to sit comfortably while holding the baby.

Eva was hungry before take off thus I fed her and she dosed off and woke up after half an hour played with her and again she slept after 10 mints and was sleeping then throughout hence I didn't feed her again. She was all ok.
