S.M.
I'm a former flight attendant, I have three boys and I have traveled with them all (all three by my self) from early on, I will first say that I agree with the poster that said as a Mom it is your job to entertain your children while traveling, save your nap or magazine for another time.
with little baby of 6 months, it is easier to travel when the flights are not crowded so that you can have an empty seat next to you for you infant carrier, which I do recommend!!!! or buy a seat for your baby. Safety is a priority for me! second have lots of food (breast milk or formula or what ever you use) you never know when you will get stuck, delayed or diverted, I use to carry the whole can of formula... ( I breast feed and supplemented with formula, but that's a whole nother issue) bring one or two toy items that might interest your child and one new one, don't bring to much or you will just have more to keep up with.
the reason it is recommended that you feed your baby on take off and landing is because the sucking is what helps babies clear their ears, landing has more of an impact on the ears than take off, always be prepared for landing.
I will share this little story with you about feeding a baby on take off, I was traveling with my three boys, they were 2 months, 4, and 5yrs at the time, my two older boys had to sit behind me and I sat with the baby with a business man in the aisle seat and the baby seat in the middle, I sat by the window. I knew I was planning on nursing my baby during take off, so I began a conversation with the business man,( he was very good looking) he was kind and a father of a young baby, his wife BF so I figured I wouldn't offend him by BFing my baby in front of him, so I get all set up to feed as we are taking off when my son pulls the blanket off and pops off the breast just as my let down started and milk went everywhere!!! even on the nice business man sitting next to me! so I'm trying to get the baby back on and get covered up, giving the nice business man something to wipe up with.... lets just say my advice is don't nurse on take off and landing, put the baby in his carrier buckle him in and give him a bottle or pacifier! yes this is a true story, but I hope it made you laugh a little, I still laugh about it!
traveling with children is easy if you are prepared, yes I did have one of my boys cry for 30 minutes during a landing once, BTW crying also helps them clear their ears so don't be afraid to let them cry if they need to, I've had ear pain before and I cried too! Traveling with the infant carrier is good because it is something they are familiar with, and they have an expectation of being in it. it is hard to "hold" them in you lap for a flight, not only will you get tired they will too! just have food and visual stimulation on hand and enjoy your trip!
