We live overseas. Parents live in two former industrial cities about 150 miles apart. Neither sets of parents have houses suitable for a small child. The baby will be about 15 months at the start of next summer. A moving base camp where we start in one city and pootle over to the other, maybe taking grandparents along for a few days at each end, feels like a brilliant idea. No need to cart everything by train or worry about car seats, one lot of baby proofing without offending anyone, and a bit more of a holiday than staying in the suburbs. Is this actually a good idea, or is it sleep deprived madness?
