Sleep co-ordination

Their mammy and daddy have gone off to a wedding and left me and Maeve Don't Blip Me to mind them. They are supposed to sleep tonight but their body clocks are not finely tuned. They have crashed out on us. Does this mean a sleepless night ahead. You can't get gripe water here any more, that used to send children into the land of nod in double quick time.

No plan B.
