Hello there,

What is more worrying here is the high grade fever as this age group is susceptible to febrile convulsions.
Please ensure that paracetamol is given along with tepid sponging to keep the temperature in the normal range.
Adenoid hypertrophy is common in this age group and this gland continues to grow in size till around 10-12 years of age.
However excessive growth can cause mouth breathing and sleep disturbances. since you have not mentioned anything related to this you need not worry.
So wait for the antibiotics to act and complete the course. In the meantime ensure a good fluid intake for your child and encourage regular sips of water and juice.

Take care.
