I paid for a 3rd seat for my daugher (20 months) so does she get all the rights as a adult? Like a carry on and a personal item and a checked bag? I mean I read all the baggage stuff for contenetal airlines but it just said one personal item such as a diaperbag , stroller, child seat ( which we are not taking to much to carry and worry about. but that pertains to me . so if I was to have 3 checked bags, 1 stroller , my camera bag , my new mickey bookbag ( LOL! ) and my daughter's teddy and sippy . Would everything be fine? Oh yeah she has to drink pediasure 3x a day so can I put at least a extra one in my bag? (for me , husband and daughter)

I know I read the site but I just like to hear from other people who went threw it.

If you purchased a ticket for her, then she is allowed the same amount of baggage / carryons, etc as anyone else. Also, I dont think a car seat counts towards any of her luggage / carryon counts, especially if she is going to be in it.

As for the pediasure, I dont think you will have a problem bringing it on as long as the TSA agents see your daughter and you make it known that you have them for her use. Also, if the containers are unopened, it will be almost a non issue. We have not had problems bringing multiple juice boxes with us for our son.
Others may chime in with their experiences.

We just flew last month. 2 airports that are pretty tight with security.

Stroller does not coundt as checked bag. You will check that at the gate. They give you a little tag and you take it right to the plane.

Carseat... Use it on the flight. It will need to go through the x-ray machine. If it does not fit it will need to be patted down by a TSA agent.

Your daughter gets the same baggage allowance you do + a diaper bag. My DD had a diaper bag and Tink back pack with no problem. I had a carry on as did my husband.

Liquids. We flew out of JFK with a bottle of milk in a bottle. I was given no problem at all. But I would empty the sippy before security.

You should have no problems at all.

Does anyone have more info on bringing juice boxes through security? My 3 year old is done with a sippy cup, but if I could pack a juice box (unopened) that would be great! If anyone has an experience with this I would love to hear about it. Thanks!

From TSA.gov (http://www.tsa.gov/travelers/airtravel/children/index.shtm#4):
Medications, baby formula and food, breast milk, and juice are allowed in reasonable quantities exceeding three ounces and are not required to be in the zip-top bag. Declare these items for inspection at the checkpoint. Click here to learn more about 3-1-1

All items including formula, breast milk, and juice will be inspected, however, you or your infant or toddler will not be asked to test or taste breast milk, formula, or juice. Our Security Officers may test liquid exemptions (exempt items more than 3 ounces) for explosives.

You might print that section out in case you run into a TSA person who doesn't know the policy.

Juice boxes:

I flew out of SLC in Sept 07 (after the new "ok to bring juice/milk for child" rule was in effect) and the SLC TSA's didn't care.

Same trip, but from Atlanta and the TSA's wouldn't let me take it. So I think the above recommendation to print the official policy and have it in-hand is a good one.

Car Seats:
Make sure it's a FAA approved car seat.

Have fun!

Juice boxes:
We ended up taking 6 boxes with us home from MCO during our last trip. They were still in their shrink-wrapped packaging. We presented them to the TSA person at x-ray and pretty much said that if we had to throw some out we would comply. They let us take all of them with no problems.
