Evening all! Sounds like sick babies all around at the moment, M is in on the act as well.
She's had a bit of a tummy bug over the last few days. After waking every hour or two on Thurs to Fri night, she had a mouthful of breakfast, threw up her morning bottle, refused lunch (including the drink) and threw up her afternoon bottle too. I called the HV who advised I see if I can get an appointment before the doctor's surgery closed for the weekend.
Managed to get one and the doctor diagnosed a slight bug as M's temperature was slightly up. Advised Calpol and small amounts of food/drink, but if throwing up and not drinking continued to go to A&E as dehydration might become a problem. 
Fortunately the Calpol seemed to do the trick and M's only thrown up once since then and has no dehydration symptoms, though she seems to be eating and drinking a bare minimum. She struggled to settle yesterday evening and screamed herself into a state for several hours before she finally dropped into a whimpery sleep. :(
I wasn't sure whether the symptoms might be linked to teething? The HV said though that normally teething doesn't cause vomiting, and I can't feel any evidence of imminent tooth arrival. It probably is just a bug, we were out and about quite a bit last week as my parents were visiting!
I'm not sure if any of that helps you and G at all, Needle? M has seemed mostly ok in herself over the last few days, just a bit sleepier and clingier than normal.
For the cost of embroidered booties, Monsoon do some which seem to be around £10? I got some lovely ones from the outlet last week for £3-£5 which I thought was a pretty good deal... So I guess maybe somewhere between £5-£10, depending on the fabric, amount of detailing, etc? Yorkshire is cheap though, so you can probably add a premium on that for being London. 
viksam, don't worry too much about one missed bottle, it won't do D any harm. He would let you know if he was starving hungry and hold out until you could make with the bottle. :) M has accidentally missed a bottle or had a late meal on a couple of occasions because I/DH forgot she hadn't eaten yet
, so you're not the only one to do it.
