My in laws have my 2 kids most Sundays for a sleepover as that works best for them and our childcare routine. Occasionally my DH will stay over with them as sometimes he works in an area which is closer to his parents house.
I gave myself a massive dose of mum guilt when I realised I actually love being in the house all by myself. I am happily married and the kids are the absolute lights of my life of course. But I love being on my own. I'm ashamed of myself!!
