i used to baby sit my neice and nephew and used to get about £3 for a whole evening - i quit at 15 cos my brother was a tight arse lmao.
So far my mum has baby sat for me and not charged, my neice (now sixteen!) and little sister (19) have both offered, but i think ill wait till Hannah is older. Dont feel confident enough to leave her with someone who isnt my or OHs mum!
