ok ta she actually went to sleep without her bed-time feed, to my surprise. Still not sure what to do about her normal 10.30ish bottle-but might just leave it if she doesn' t wake up. but she'll be hungry/thirsty during the night-will have to feed her I guess...
Has she only thrown up once? If so it may not be a virus/bug at all. Some children have one or two episodes of vomiting due to various factors (such as coughing, shovelling dinner down too fast etc) only time will tell.
Good luck whatever the cause, but agree 100%with those that say offer small bf as requested.
Definitely breastfeed her, it'll re-line her stomach, give her easily absorbed calories and fluids. It's the best thing she can possibly have!!!
You may not get it, mine have had bugs that I've not come down with, but you will make antibodies to what ever she has, which will help her fight it off quicker, so boob her as much as you can, little and often.
