We're in the same boat. My LO is 23 months old and had a very difficult birth and a hard start in SCBU and has always been behind. Fortunately we've been supported by a wonderful consultant from day 1 of her life who has followed her through feeding difficulties and breathing issues.
Now her main problem is developmental delays (6-9 months behind in over half the areas of assessment) and we've just had our feedback from the big multi-disciplinary assessments with various agencies and found DD is being referred to Inclusion, portage, Speech and language therapy which will include Makaton signing to help her communicate. It's hard to absorb (and I work in education so obviously it wasn't a massive surprise- but harder being on the other side of that meeting) when they talk about getting one to one support in for nursery to help her. She doesn't seem *that* bad to me. Obviously she is speech delayed and has a few...well red flags for me in terms of her behaviour, but nothing terrible so I am surprised at the level of support offered. But in a very good way.
We're waiting on an MRI scan now to check for brain damage which all sounds very worrying even when we're trying to be positive. She's such a happy and friendly little girl and a diagnosis doesn't change anything. But the side of me that *knows* how it affects your future is definitely worried.
Anyway, that's my babbling story. well done if you stuck through that!
