Oeisha I know exactly how you feel. I had this for 2 weeks solid about a month ago, and absolutely nothing shifted it - not not-eating, not eating, not what I ate, not Rennie, not almonds, not drinking more/less. It woke me up at night too. And one day I just woke up and it had gone, and it hasn't been back... Don't know what that was all about but I sure hope it stays away.
My two-penn'orth to the baby cosmetics debate, FWIW. For my other two I used a mix of real nappies and Pampers (real nappies for just bumming around (haha) and disposables for nights and going out for longer, just for convenience). I got some nappy liners for the real ones but they were so scratchy that I just used the nappies alone (with pants of course) and washed them on 90 deg. and they were fine. Can't get much in the way of that sort of stuff here so I couldn't try different types. I have Cotton Bottoms, which are basically just squares of layered fabrics that you fold into 3. I'm sure there are better on the market now, but I'm not splashing out any more.
On the bum I used Bepanthen (the tube with the pink stripe), which I found was amazing, neither of mine ever had any rashes or anything, and any random irritation was down within half a day with extra applied. I tried Sudocrem but couldn't get it to spread evenly so went back to BP. We still use it as ointment on scratches, grazes and irritation now. It's expensive as hell here, but I don't care. But like someone said upthread, no two babies are the same and who knows, all my theories may be blown out of the water this time...
Have to admit to using packaged wipes, purely for convenience (didn't have a problem with skin allergies so bought whatever came to hand/was cheapest), but fish your mixture sounds good and really appeals to my hippier side so I think I'll try that as well if I can get all the ingredients. Can I ask what EC is? Is it where you learn to recognise baby's signals and hold them over a toilet/sink/bowl to wee/poo instead of putting them in nappies?
For bath time camomile tea in the water (we have really hard water) but I don't remember what cosmetics. I was going to use Olive oil post-bath but the GP said she'd heard of lots of allergies, so I didn't, used some local stuff, but I want to change dr for this baby for various reasons, so may try the OO this time.
Ugh, what an epistle. Giraffe how are you this morning? hope things calmed down for you.
