Has anyone else never left their DC overnight and doesn;t want to?

[Gateau]

Our DS is 21 months old and we have never left him with anyone else overnight; nor do we want to. Yes, DH and I have our nights out and grandparents babysit but we haven't felt the need to have him kept overnight.My brother who has two sons keeps telling me staying overnight will be harder for him as he gets older; do you think that's the case? TBH, I can't see us wanting to do this in the near future anyway.
I keep reading on here about parents going away for weekends or nights, sometimes even a week without their DC. Are we the only ones who don't do this?

The first time DS stayed overnight with my parents I was in hospital having my ruptured appendix removed. He was 9 months old and had been fully BF until that point. I was heartbroken, couldn't stand being away from him and insisted on being discharged the next day. (Meanwhile DS had been having a great old time at Granny's glugging away on newly discovered bottles of formula).
Since then he has stayed with them overnight about once a month. No he's not a particularly good sleeper but I am a lone parent and feel I would have gone completely insane from sleep deprivation without this help. My parents have been happy to do it and it has been good for their relationship with DS (he does not have overnight stays at his father's - contrary to popular belief not all lone parents have 'weekends off').
Surely this is a case of horses for courses people! I'm sure that if I had a helpful partner and could afford babysitters DS would have spent less time with his GPs - but actually he might then have missed out on some really lovely times with them.

Yep, over here, I left my dd at her nannys, didnt want to, her nanny couldnt be arsed with her for the first 18mnths, said she was boring and would have her over when she was more fun!!!!

Anyway, my dp tries to please his excuse of a mother and now my dd stays at nannys, rips me apart every time, but she comes to no harm, and she enjoys it, she never stays any where else but there, she's 3 now.
