What are the general regulations for bringing baby food and other necessary baby things on board a plane?

I'll be traveling with my 7 month old daughter next month and I'm unsure of the general regulations for baby food and other things necessary. I've flown with her before, but it was on a military Space-A plane and the regulations are different. I've never flown commercial with her.What are the general regulations for bringing baby food and other necessary baby things on board a plane?Baby food is usually fine, milk/formula through can be a problem, normally they will not allow it. If it is dry formula it will be allowed and you have to get water after going through security. Things like diapers, toys, etc... are allowed.
