I need to vent for a minute....
There is a vast difference between the duties of a babysitter and those of a Father.
Babysitter: Paid to watch a child for the short-term
Father: Chose to have a child, and therefore is expected to watch the child for the long term
Babysitter: Paid an hourly wage
Father: Chose to have a child and therefore is expected to watch the child; if wages are stupidly requested they should be forfeited to the Mother
Babysitter: Seeks employment in childcare
Father: Chose to have a child and therefore is expected to watch the child; it's not considered a favour by the Mother when he watches the child for an evening; the Mother is repeatedly annoyed by the insinuation that she spends too many nights out - two nights a month over the past 6 months isn't a lot... the Mother spent every night at home for the 2 years prior - most of which she took care of the child alone
Babysitter: Is not a parent, and gets to go home at the end of an evening
Father: Is a parent, and should enjoy having his child over for a sleepover; when he whines about not sleeping much then he should know that the Mother will not be impressed - she had her first 8 hour sleep in 3 years last night....
