Number3 and Fleurchamp - My exH has had the DC a grand total of six days in 2014, so £300 a month would be like winning the lottery, although I would then expect him to renege on our joint loan, although I would still be better off!
My exH has completely dismissed any responsibility for the DC, he literally sees them 6-7 hours a week, which is split between an hour or two during the week after school, and 4 hours on a sunday afternoon, he's not interested in any more than that. He struggles to even call them these days, especially if he is going out. I literally had 4 nights out last year, one of those was my birthday dinner for my 40th!
My OH contributes more financially and emotionally in terms of support for DC, although we always make it clear to DC he is not replacing their dad. Over Christmas DS who is 9 asked if OH will be proposing to me, because he fancies changing his name?! Breaks my heart really, but he is old enough to see what his dad is up to.
Fleurchamp I work for an American law firm in the City, relatively small office and we get a grand total of 12 weeks full pay, then a return to work bonus which is split between six months. Admittedly it is more than the statutory maternity pay but not enough for me to be off work for longer. I'd love to take at least 6 months off, but don't think we'll be able to afford making up the shortfall, so I'm looking at 4, maybe 5 months maximum.
