The ideal way to move with small children is to wait until they turn 10.
Next best would be to have them stay in a cozy, safe, distant place until the entire move is over.
Third would perhaps be to have good weather and health, and somebody free to watch them for you on site.
Move about ten more notches down the list and you will find us: in the middle of January, tired and cranky from all our pre-moving activities, and pausing in our work to discover that somebody has just unpacked a box we just packed or exploded through a diaper because we forgot to change him in the last five hours.
We know it will end sometime, and we are very grateful for the help we receive. But right now we just want to go home.
