My 3yo is constantly ill this winter. Colds, chest infections, sickness...everything. She seems to take a long time to get over most of the illnesses she picks up too. All the other children her age seem to bounce back or get through everything fine.
She does suffer with a wheeze so colds hit her harder and has has been hospitalised in the past. She's been in nursery since she was 1 (on and off due to lockdowns) so I'd expect the illness to slow down? anyone else finding this winter worse for illness in their little ones?
