See http://www.tsa.gov/travelers/airtravel/children/formula.shtm from which I'll quote two paragraphs:
Baby formula and breast milk are allowed in your carry-on baggage or personal items. You can take these through the security checkpoints and aboard your plane. However, you must be traveling with a baby or toddler. All items including formula or breast milk will be inspected.
Please note, that juice and all other liquids or gels are not permitted.
OP wanted to carry on "sealed Horizon milk singles" not Baby formula and breast milk.
Again, milk can be purchased for consumption in the airport terminal. And milk is available during beverage service (at least it is in American and United, and I suspect on all other airlines). Sure there might be a catering glitch now and then, but that would be the exception, not the rule.
OP here. Well maybe I'm just an idiot, but I did think that this exact passage was vague due to the inclusion of "toddler". Toddlers, generally, don't drink formula so it wasn't clear to me that cow's milk wouldn't necessarily be included if you were allowed to bring aboard beverages for toddlers.
I didn't intend to start a debate about this. I just wanted to know what constituted a "toddler". I'm not planning to sneak milk on board. I'll buy milk in the terminal and throw it away before we board. I'm not overly concerned that we won't be able to get her something to drink (juice is a special treat for her, so I'm sure that will make her happy).
This is just a different situation for us because I'm one of those moms who always has a little lunchbag with milk, bottled water, snack, etc. so my DD always has a healthy snack available when we are out and about for more than an hour. I guess that my DD is use to milk on demand (something we started when she was a nursing child...hmm, now I wish she was still nursing, but that would be another debate I'm sure
