I am part of a nomadic couple (3.5 years and counting since we had a fixed abode), that will have a nomadic newborn in a few months. The plan is to remain nomads once the baby comes along, but we have discussed every possible option. There's no way for us to know exactly what it'll be like (just as there's no way for OP to know what their 9 and 11 year old will be like in 5 years), so we're playing the future by ear and trying to plan for as many scenarios as we can.
