Hi, I don't think I've ever explained my situation so will try to do that a bit first. My ex dumped me shortly (a week or so) before we found out that I was pregnant, was a complete arse througout the pregnancy (I'm not going into details as it will make me sound bitter and I can't deal with constantly rehashing it, but included being threatening and generally shouting at me lots), refused to go to relationship counselling to try and resolve things, and has been living apart from us other than a few days after DD was born when he stayed at mine. He has had fairly regular contact with DD as I hoped she would have a relationship with her dad, even though I think he's an awful male role model so have been ambivalent about the whole thing (a lot of my friends thought I should not tell him about the pregnancy and not let him come to register the birth after how he'd behaved [emotionally abusive and controlling, they reckon], but stupidly I did anyway). He has been ok at parenting DD, though sometimes has unrealistic expectations (e.g. that she actually understands that she's not supposed to do something or is 'attention seeking': she's 10 months old!). We're now about to embark on mediation to get a more formal contact agreement and I'm hoping an arrangement to sort out more equitable housing/finance (he's living and entertaining his 19-year-old girlfriend [he's 36] in a quarter of a million pound flat in a nice area of our town; DD is living with me in an ex-council towerblock next to drug addicts at extortionate rent which I actually can't afford to keep paying for as I'm on a PhD stipend and council will not help at all).
The situation on which I seek the wisdom of the internet, though, is this: he's offered to have DD overnight on Saturday so I can get some sleep (whether neighbours will also allow this by refraining from noisy parties is another matter, but it's the thought that counts...). Part of me is greeting this with the glee that comes from intense schadenfreude: we'll see if he's still so smug about being a part-time dad after a sleepless night. The other, less nasty, part however is terrified that it will be traumatic for DD as she is used to being with me 95% of the time, and always overnight. She is still partially breastfed and tends to feed (for comfort rather than nutrition I think, as not long feeds) frequently during the night. I am fine with him giving her formula if necessary, and I am not worried over one night about losing supply (should I be, though?), but I am worried she will be upset. I generally believe in a sort of semi-attachment-parenting type system, though I am not 'crunchy' enough to do the whole lot of it, so I am concerned about whether this will completely mess her up emotionally. Should I be, or not? I would really love to get a full night sleep for once (it's been over a year as didn't sleep well in pregnancy...), but not at the expense of DD's wellbeing. It would obviously be a different matter if he was a resident dad as she'd be more used to having him around at night, but she really isn't.
Argh. Help?
