My little one is almost 3 and he used to hate and scream when taking a bath, washing his hair and sitting on the potty. Now he loves it and even asked to take a bath but…. Now he has tantrums when we don’t do his way throwing himself on the floor and calms himself in less than 5 min, even at the nursery as he can’t transition from one task to another, throwing toys when he is frustrated and screaming and crying. He is a very smart boy knowing lots of nursery songs, the alphabet, counting to 100, all the shapes and puzzles, and colours, he even knows what happens next when we read to him stories and memories them. The nursery sent a report so he could be assessed….
My son was the same and was autistic. He does not like new experiences so I have to either demonstrate on myself or his brother what to expect. A lot of coaching and verbalizing through stuff. He hates water in his face in the shower and have to count down to it and even then for like 2 seconds. Showers take a minute 🙃. He doesn’t like the tooth brush either I switched to a U toothbrush so at least more area could be cleaned at the same time 🤷🏽♀️ you do what you can. One thing I’ve learned is it’s not personal with him it’s his own comfort so lots of patience. Scariest thing is getting assessed after that resources open up to help support you and your child.
Get her assessed, only sure way to know, then you'll never be wondering and wishing you did somehting sooner if she has 🙂
