Jin,
Happen to read your post during my lunch hr (lunch in today), Just a quick reply from me, hope this helps.
1. Yes, baby should still on FM 2-3 times a day on top of solid meals, so must bring along the FM, few milk bottles (just in case u cant wash them thoroughly after each use) and thermos.
2. They can start eating some table foods, I am sure u know what to give him.
3. I brought along a slow cooker to cook his meals (was on F&E) when time permit. Else I gave him retortable baby foods, those can simply heat up by using hot boiled water or microwave. Suggest u let ur boy try them out first just in case he reject them. Besides, I also brought a lot of baby snacks and biscuits, my boy simply loves them.
4. Not recommended, but in the worst case for 1-2 days should be fine, definately not for long (I presume u will go for at least a week?).
And Nov should be winter in Korea, dun forget to do ur best to keep ur boy warm. Having say that, please bring along few common medicines with u, such as paracetamol, brufen, med for runny nose, diarrhea etc, just in case.
