Oh my goodness leni I do hope they find out what's wrong soon. Must be awful for you having lost he ability to do simple things like that for your DS :(
DD also has dry blotchy skin, mostly under her neck and the top of her chest but also sometimes around her chin which I had just put down to drooling all the time. I've been using Vaseline but I'll keep an eye on it.
eco I finally started weaning DD today as I was getting totally freaked out by the way she was just STARING at our food and our mouths the past few days especially. I was putting it off because I was being lazy!
Going for the mix of finger food and spoon feeding, she had baby rice at lunchtime, and because I've been so disorganised she was just in the bumbo on the kitchen floor. I started off with very runny baby rice but that was a bit nothing really so kept adding more until it went extremely thick and she was having a hard time eating it, bless her! I stopped after that 
Then this evening she had some mashed potato. As lumpy as I normally make it (!) with a knob of unsalted butter and a splash of whole milk. She sat up happily in the highchair for it and I stupidly put it in a little bowl but the first thing she did was to grab it and try to stuff it in her mouth! I took the bowl away
She really enjoyed it and was just slurping and sucking it off her fingers when there wasn't much left!
It was lovely just having her in the highchair up at the table with us and not down low in her bouncer or sitting in the bumbo. I forgot to put a bib on her though and must've chucked all the great plastic ones we used with DS so I'd better get some pretty quickly.
Hope we all have a good night's sleep tonight. With or without medicinal aid!
