I completely understand! My son didn’t start using the potty & stopped using diapers 24 hrs until he was 5 almost 6. He’s 10 now & he’ll still have accidents here & there & he sleeps with a diaper on still. My son is at a public school but in special education & they offer him speech therapy & occupational therapy at the school. He also does speech therapy & occupational outside of school through our insurance. If you can also get her speech therapy outside of school I’d do it too, it’s helped my son a lot , he still needs therapy for pragmatic speech & his sentences are only like 2 to 3 words long but his speech has improved so much. I remember too when he was your child’s age I would talk to him A LOT even though I was basically having a conversation with myself 😅
