I noticed last night while stroking DD's head to get her back to sleep that these is a great big, hard, longish feeling lump directly behind her right ear, you can see it but it's not red or causing her any pain (she slept through me poking it) it's quite warm to the touch. I checked the other ear and there was nothing there but this morning there is one there too, it's much smaller but certainly there behind the other ear.
Is it glands? She's not been unwell, she's 2.
