When my oldest daughter was 4 she had chicken pox she had 6 externally the rest were internal as in in her ears on her nether regions etc.not overtly noticed, her brother had them also and the were confirmed so its possible that she may have them as far as I know you need to guard agains German Measles that can cause major problems.

If she is feeling unwell give her panadol as well as her antibiotice and ask her what she'd like, if its OJ, milk add a raw egg and blend well it will help boost her and you cant taste it.

Best wishes.

maybe just keep an eye on the spots for now but as for her heavy breathing and temp all i can suggest to do is keep putting her in tempid baths and be sure to wet her hair as this will cool her off (the head is where the heat is released) and for the breathing you may need to sit in the bathroom with her and have the shower going so the steam can help her breathe better but just be sure not to let her sit there to long as it may cause her temp to go back up but make sure she keeps up with her fluids also, its hard i know i hope it all works out for you

good luck with your pregnancy

my youngest had a simliar thing spots all over her legs  and was not drinking much i gave her dimtap and nurfoen one in the morning the other at lunchtime and she got lots of sleep and i thought josie had chicken pox and went to my friends house (checkymonkey) and she said you get chicken pox on the tummy or bum first so it wasnt that it went away after two week s i also rubbed vix on her clothes and on her teddy she hugs when going to sleep made it alot better for her
