Is that normal? Dc (aged 17 months) started nursery 6 months ago, and has had 3 bad chest infections that required antibiotics, time off work for me, and she's miserable each time with temperature, running nose, rattly cough. The cough then tends to hang around for weeks, keeping her awake at night.
Is there anything I can do to boost her immune system? And is this always the way with nursery?
