grandma (MIL) sometimes has our 3 nearly 4 year old overnight. Only about 4 times. She lives alone and puts him on cushions on the floor (there is nowhere else) and sleeps beside him. He has wet the bed on a couple of occasions, and one time rolled off and peed on her white rugs.
She works from home, so I understand the difficulty there, plus the rugs are heavy and she cant manage the laundry. She is insistent that we put him in nappies when he sleeps over. He hasn't worn them for nearly 2 years, and I doubt it he will keep them on. I don't want to do it as it seems regressive, especially as although he kept dry at night for 3 months, he has been wetting the bed quite a lot at home recently. I am happy to resolve the issue by using a travel cot, (if he would fit in one) but he is heavy and and she has a bad shoulder, so doubt that would work. Am I being unreasonable? She seems to think so.
