tay has had this numerous times. always have v &D best solution we found was lots of baths, 3 a day in a nice luke warm bath and bubbles, not to many clothes, no socks as they irritated her blister son her feet. ice blocks as she gets the blisters all through her mouth and we minimise dairy while she is vomiting.

panadol and nurofen were our saviours.

otherwise im sorry its hard i know but it will get better

tays lasts anywhere from 2 days to 2 weeks depends how bad she has it temp usually goes after 48-72 hours, then she is just itchy and sore
