To be fair I've benefited from my sister having kids already. My mum didn't do overnights with her kids for years and if she did babysitting it was in my sisters house. She only started doing a little bit of childcare for her once the youngest of her 3 was 3 years old I. e. 7 years after the first grandchild was born.
It means when Lil came along my mum was much more confident about little babies and didn't want to miss out. She started taking her for 1/2 a day a week from 7 months and as a result the pair of them have a great relationship.
Add to the mix my sister who would have been one of those 16 kids and counting women if only she could have afforded more kids.
Plus we've got the world's most sensible 16 year old 2 doors down who happily babysits - her mother keeps telling us to stop paying her so much because she'd do it for free.
Sorry you guys have a lot less. My brother is in a similar boat as he lives so far away. He originally booked a babysitter through one of those childcare websites but has since negotiated to book her directly so it saves them both money.
