‘Doctors don’t tend to diagnose allergies like hay fever until children are older,’ says Lucy, ‘but I see plenty of those allergy symptoms in my summer baby sleep clinics, with streaming eyes and runny noses making bedtime more difficult.’ And you don’t have to wait for a diagnosis to do something about it. If your youngster is being affected, invest in an anti-allergy mattress, and hoover the house daily to get rid of the pollen that finds its way indoors. If she’s been outdoors, then she’s likely to have pollen stuck to her, too. Undress her in a different room to where she sleeps, and wash any exposed skin with a damp flannel to get rid of the pollen. ‘Have a chat to your GP about whether this could be a pollen allergy, too,’ suggests Lucy.
