Just reading through and catching up on everyone's news, and I agree with leni.
By now we all know our babies, know their little quirks and normal routines, and more importantly know if something isn't quite right with them. DD is for the most part a fairly easy baby, and for example I've learnt that for her it is normal to go 7 days between dirty nappies when ebf, or 4 when on mixed feeding. It was much more often in the early weeks, but there isn't a problem, it is just how she is. Similarly with feeds, as she is now fed half and half it is impossible to count the number of floz taken, so I don't worry about it. I have noticed however that if she has a bottle at lunchtime she will down 7floz, but at other times she is much less hungry so may only take 3floz. She also goes 10 plus hours without a feed at night now, and that is absolutely fine too. I think we should all go with our instincts.
Stormy - I hope you find a more interested and sympathetic GP and get a referral. Just go in and demand one, say how worried you are. If it were me I'd take DH and present a united front, it makes you look more determined. As for your HV, I'm speechless. Do these people actually have any qualifications?! Good luck, and if that fails any chance you could stretch to a private consultation? I know you shouldn't have to, but if you get a problem identified privately the NHS will at least pick up the baton from there on in and treat it.
A couple of really long shifts here, as DH is travelling for work leaving me for 48 hours at a time. It's getting easier though as the tiddler is settling into a pattern which works for me, and more importantly for her.
