Same problem...made it to 40 as a single, free and pretty wild bushman...and then got married and have two small kids.
from an African viewpoint....a) The truck had better be very well stocked- espeicially with liquids. My daughter is extremely fussy and in a country where food is often short and individual items as frequently out of stock as in- this makes life doubly difficult. When we find something she likes it is almost guaranteed to be the last stocks and you will not get any more for 6 months.
b) better to stay than to move. Again, becuase Zimbabwe is such a train smash, I hold at least 6 months supplies of anything I really want to use...eg- I like tuna fish...so have 80 cans in stock- I drink black coffee all day, but like the first cup with condensed milk...so have 20 tins on hand... Have 20l (about US 5 gal) of the fruit juice concentrate my daughter likes...my son will not touch forula so basically his dietry needs depend on mommy being well fed....so have 50lbs of rice, the tuna, tins of ham, never less than 50lbs of dried jugo beans on hand...etc.
With two small kids it has to be by car or not at all- I could get both Kids into the Piper cub, but suspect mommy would have a few things to say about being left for the second trip

The summery is then- to see trouble comming far enough in advance to bug out while vehicle travel is still possible
