T., first off we've all been there, so you'll have other mommies support. Remember to double check your diaper bag that it does not have any "contaband", I accidentally left a pair of kids scissors in my one time and when I was asked to step aside, it was the most nerve recking thing and with a baby who's crying at that point, is not fun. Pear down your belonging as much as possible. Look at what you have and make sure you have everything but not too much. I would also suggest, a change of clothes for you and for her. My dt had a bad case of diarria that just seem to come on as soon as we walked into the terminal! 3 sets of clothes and we weren't though yet. When you get in the plane check with the flight attendant to see if there's a "changing area" in the lavs. If tylenol is not working on her have you tried motrin. I was never a motrin mom, I always stuck with Tylenol myself, but diff babies react differently to meds. I would bring some on the plane with me. Also try to hold off on feeding her until its right before take off and right before they start to desend. That's really the only way to prevent the ear thing, they need to constantly suck on something. Think about bringing a bottle for water. 4 hours is a long time to hold onto a baby, I wouldn't be afraid to allow someone to hold her for a bit. If nothing a flight attendant who is caring. I've had some that just gives you the dirty look, which I was not going to have any of that. I paid for my tickets she does not need to treat me or my baby tht way. Lastly, don't be nervous, bc your baby can probably pick up on that. You need to take the lead and remain calm. Hopefully its Sun that you are traveling and not today Sat. Good luck and enjoy your visit home. A.
