You are amazing grandparents! I vote for the one grandparent sleeps in the child’s room and alternates every night. At least you will be getting a good nights sleep every other day. The grandparent who got to sleep undisturbed gets to do the morning breakfast/school run, leaving the tired grandparent to have a lie in. Childproof the room as much as possible, if possible put most of the toys out of reach and only have a few out...teach them that the toy boxes come down/out at a certain time and set an alarm clock for when this happens. Just leave out a few sturdy books and soft toys for quiet play if they get up too early. You could also try cutting out any afternoon naps they might have and instead introduce reading time or TV time. If they no longer have naps then you could try putting them to bed a bit later (although I know you’re probably watching that clock trying to hang on in your exhaustion until bedtime as it is!). You can also try those projector night lights that project rotating images on the ceilings and play music that they sell for babies..they work for older kids (and even adults) too!
