Hi everyone, I am the OP. I haven't checked this thread in such a long time. Sorry to hear of all the problems with your children, at the time when it was happening (so many years ago now) I felt alone and that noone else went through the same thing. The only thing you can keep doing is keep pushing and keep advocating for them. Thought I'd give you an update as my daughter is now 6 (7 next week!).
She did get referred to a paediatrician, but like the previous poster, they said she was healthy and didn't see her again. It was frustrating because all they cared about was that she hadn't lost lots of weight (she would make up for it in between episodes with her eating) They wouldn't even do a blood test, said its something they don't like doing on kids so young. She became seriously unwell in hospital when 2 years 4 months, but something that may have nothing to do with the fevers so will spare you any details (ironically she then had to have blood tests every week for 3 months). We thought it was another episode so tried to ride it out, so I would say it is important to keep taking your kids to the dr every time they are ill. As thinking it was one of her episodes masked what was actually wrong with her at first (which is what I was scared of each time she had an episode and drs said it was just a virus). Especially if it goes on for a few days. Don't be overly paranoid but do make sure someone sees them, just so there is some accountability too. I kept records of when she would have fevers but drs didn't seem to care unless they had an actual record of seeing her each time. It was as if they didn't believe me.
After her hospital admission and subsequent surgery she needed she fully recovered. Fever free for a few months but then ended up getting recurrent tonsillitis. 20 bouts of tonsillitis later over 2 years and lots of misery and she had them out. The drs decided this not because she suffered from tonsillitis every month (!!!) but because it caused sleep apnea. It was frustrating and upsetting.
But since having them out, no fevers, no illness apart from colds. I have a fully healthy (finally!) almost 7 year old! She has been fully healthy since she had them out at 5 years old in 2020. Her first 5 years were turbulent and full of ill health but now you wouldn't be able to tell.
Could she have had something underlying with all these fevers all along, I question this a lot. Could it have been her tonsils? Because she would get tonsillitis every single month? It is quite possible. I mean how good of a look can doctors get at the throat when looking in a baby/toddlers mouth?
Sorry I don't have any definitive answers, I just thought it might be useful for you guys to hear our story and how it panned out. It was one of the worst periods of my life not knowing what was wrong with her and I absolutely sympathise with you all and I'm just so sorry I have no proper answers. The best advice I have is just keep advocating for those kids and look after yourselves as it is so tough caring for them. Good luck ❤
