Flying with infant & kids

I feel blessed when abrielle didn't make so much trouble to others during her 1st time travelling by air.. others than screaming happily and try to pull others hair that sitting in front and at our back.. before boarding. We really worry she will crying all the way from kk to kl.. haha thanks GOD its never happened. We feed using her favorite milk bottle after take off & before landing to make sure air pressure in her ear cleared and she won't crying after that.
I think some of us have experienced some that can be called flyin nightmare because of the air pressure inside ear..either we suffer because of its or others suffer from it especially baby & know kids.. if we have this problem.. we will suffer a lot because its feel like our ear will blow.. if the kids & infants,  they will crying because its so painful.
When I traveling with a little 1.. remember this.. try give them something to chew.. or suck.. its will help them to release air pressure inside ear.  Tonite when I fly back ti kl.. got a big group in front of me and 1 of the baby crying painfully after take off until after landing.. and surprising.  The parent never gave her any water or milk during 2 1/2 hour.. aiseh.. came on la... if they feed her with something that she can chew or suck. I'm pretty sure that she won't crying all the way from kk to kl. Pity her.. and also pity to the parents that don't have any idea whhhhhhhyyy their baby crying loud. If you travel by air next time. Make sure you have something for you and your companion to chew or suck.. good luck.
