Going on a family trip overnight, how do i feed my son?

get a pump....and pump it under a blanket in the back seat then give it to the baby that's the only way you can do it because you have to freeze milk if you don't use it right away and you don't have anything to heat it up with.....just do it under a blanket there is nothing to be embarred about.....i'd rather you not do this but you could resort to formula for the six hours. If i were you I would just pump in the care it's better for the baby.....i hope it works out and stop stressing you'll figure it out
