Have you been to the doctors? Just thinking if he might need some anti biotics. Also have you given pain relief as we know just how horrible a sore throat is :( x
We have the same problem. Apart from yoghurt she also eats avocado out of the fridge cut into little pieces and sometimes pieces of banana.
My 17months old boy had this so I eventually too him to the doctors and she said he had tonsillitis and was in antibiotics he’s better but still has a bit of a cold x
