gp is being cautious and saying she's never seen it in an under three. dh had very bad hayfever as a child, and dd2 seems to have the worst sort of blocked nose especially at night - she did have a streaming cold over Easter, but it doesn't seem to be getting any better.
She rubs her eyes (no conjunctivitis or discharge) and her nose often, especially past few days, and sneezes when taken outside, though not all the time.
Its probably the tail end of the cold, or teething, but I can't help wondering - could it possibly be allergy related?
