Clutching, thank you for the update. I am glad your DS is improving and don't feel you have to be super cheery when actually you are scared or upset by what is happening. I'm sure we can all understand that.
Almost exactly a year ago, my DS, 17 months also, was rushed to hospital because he was incredibly sleepy and the doctor feared he had meningitis.
He turned out to have another severe infection which he was lucky they caught in time. He had to stay in hospital for quite some time and receive antibiotics and constant monitoring as he was so unwell.
Obviously it isn't the same situation. I am not you and my DS is not your son. But there are many similarities, including how anxious I felt about my DS not being himself.
My DS stopped speaking when in hospital. He also couldn't walk for a while. This was the effect of him being so weak and the lumbar puncture, along with a total loss of confidence in his ability to do anything. It was like seeing him returned to being a much younger child who wasn't him - something I found incredibly scary. I had to leave the room sometimes and breathe outside as I was so freaked out.
He was a very clingy child, who loved pressing his cheek to yours and constant hugs and I felt was "different" after his illness in hospital, more detached. He just seemed not like him.
Just to say that looking back, I now realise he - like all of us - was just completely hit for six by the whole situation. It was not a rejection of me or real change in his character, just him trying to cope. And it changed every day. Some days in hospital, he was distant, then suddenly he'd need me to be there around the clock. He was too young to rationalise what was occurring.
Sometimes I would think he was so different from how he used to be; sometimes he'd be like his old self
I am not sure that we all even started to get our heads together until we had been home a while, he began to walk and talk again and I stopped checking him obsessively in his sleep.
Anyway, I didn't mean to hijack your thread in any way. I was just trying to say that I think it is completely understandable why you feel this way and it is so so early in your DS getting better.
I don't think there is one way for anyone to react to what is such a stressful, awful situation. But I'll be thinking of you lots.
