Spotty and sleepy?

[CitrusBun]

Hi all
Looking for advice - four year old DD has around ten or so spots like these as of a day or so ago and is feeling very low on energy compared to her usual self. Does this sound like anything other than a little tired girl developing the odd spot please?

Looks like chicken pox to me

Looks exactly like how my DS's chicken pox started a couple of weeks ago

ticks all the chicken pox boxes!
