Gripe water became my best friend on the flight and it did work when the crying became too much. When I could see that clearly she was in pain and frustrated, I gave her the proper recommended amount and a bottle of water/juice to drink afterwards. She even received Arrowroot cookies (3 in total on the whole return trip) just to show her that she behaved well on that long journey and also to show her that we loved her dearly. She was very happy to see me pull out a cookie each time I felt she deserved it.
One other thing that was a huge life saver on this trip was my Boon for feeding her, especially with tight quarters and lack of table space. I would fill the Boon spoon up with the right amount of baby food, squeeze and voila! No mess, no fuss dinner. Ray and I first saw this spoon in the summer of 2009 when a couple was feeding their infant down at Harbourfront and we always told ourselves that we needed to buy it. It can be a little much - $16 might not be worth it to parents but I think it was a wise purchase.
