My 4 y old was very snotty and blocked up til at 14 months we stopped dairy. Then I noticed hearing and speech were not good and that improved greatly with grommets last June. They said speech would improve over time but the bunged up thing seems a lot worse, affecting sleep, speech - even I can’t understand his new words - and I suspect irritability. I know how I get with a blocked nose! Any thoughts? Can I try anything to clear it (must be pretty solid and sticky - I’ve always noticed he has snot stickier than Pritt stick!). Health visitor informed but it’s all about finding drop in sessions and getting referrals so it could be a while...
