DD has recently turned 2. She was very high needs as a baby and though obviously her needs have changed with her age, she remains very different to her peers. She cannot speak at all, really. She has one word that would be recognisable to anyone, but often pronounces it differently so it's incomprehensible. She is extremely fussy with food and has a very restricted diet. She has never been picked up by anyone but DH or I, she is furious if anyone tries to touch her bar us and her siblings. Even GPs are rejected - she almost fell down some stairs because MIL was coming behind her and she panicked that she'd try and pick her up.
She is complex in a way I don't see with other toddlers. For example, today she had her sleeve stuck on a toy and was screaming because it was restricting her movement (which she hates). DH is less experienced with her 'ways' and headed in to help her, which made her scream ten times louder. With things like this, I always have to ask first if she'd like help before approaching or touching otherwise she cannot cope. Contact has to be on her terms, always.
She will get extremely upset about small things - I.e. If she trips and anyone says 'its okay', she'll scream like she's broken a leg. If she's trying to get somewhere and someone else gets there first she'll be distraught. PIL can't get out of the habit of saying I'm coming to get you and going at her like they're going to grab/tickle her and it sends her into an absolute meltdown.
I don't know if she's just unique or if I should be getting these behaviours looked into and would really appreciate any advice anyone here could offer.
