Thanks everyone for your sage replies!
FATEdestiny, I wouldn't describe myself as an "attachment" parent, rather a parent who is trying to treat the baby the way he was designed to be treated. I am starting to realise that this does not always mesh well with modern life (especially parenting alone for most of the day). However, I also believe that babies need to be dependent before they can become independent. I don't mind rocking him to sleep etc, but five times a day is a bit excessive. I suppose I'd rather do this than some form of controlled crying.
scottygirl5, HomeIsWhereTheHeartIs, LowlLowl, TwiggyHeart, mrshope, OurDayWillCome Thank you for empathising! It's very reassuring to know that things changed for you all eventually. I know they will for me too, but you know, when you're in the midst of it it's unbearable. I have actually considered expressing a crapload of milk then going to spend the night at my parents' so that DH can feed through the night and I can sleep... we live in a small flat and if I stayed here, I'd be awoken by DS's cries/whimpers no matter where I slept. I'd still have to wake at least once to express milk during the night, but it'd be a helluva lot better than every 1.5 hours.
Daisy17, Goldmandra Yes, I keep reminding myself that as he develops neurologically, this will all be a distant (disturbing) memory!! Unfortunately, DS is not happy with anyone but me or DH at the moment, so no chance of babysitting just now. I might ask DH if he'll take him out in the pram for a while this weekend. It'll be nice for me not to constantly feel "needed"...
Sometimes I wonder about PND as well. Some days I'm fine (providing I get to sleep in at least 2-hour chunks) but others just leave me feeling hungover, irritated and very resentful (of DS, DH, everything...). Knowing that other people have been there really helps though. My two close mum friends both FF and have never experienced this issue.
I suppose I just came on here to vent and for empathy... if there were a one-size-fits-all solution, this forum would not exist and I we'd all be splendidly well rested!
