My 11 mo dd will not eat from a jar, only my stuff, which is lovely normally but we are going away for 2 weeks, and the first 2 nights will be a combination of ferry and hotel. Has anyone any bright ideas about how I can transport her frozen purees for that length of time? I would be very grateful. Also, does anyone have any tips about warming stuff on the move? Anything I can get on the internet would be very useful.
