I'm after some advice or friendly reassurance from anybody medical/nutrition/dietician or a parent with fussy eaters.
My son is 3 next week. Since last Thursday he has been ill with high temperatures over 39 degrees (which resolve with Calpol), and after a trip to OOH and then to GP has been diagnosed with tonsillitis (again) and is now on Antibiotics (since Monday).
My issue is that he won't eat. Not even soft food. Not even sweet soft food as bribery. He hasn't eaten properly since Thursday, and on the days that he is eating, this involves for example: half a hash brown, half of one Weetabix (breakfast times), about 6 small spoons of custard, same amount of spaghetti in tomato sauce (at lunchtimes), a handful (his hand - so tiny) of pom bears. The thing he has eaten most of is watermelon - he would normally trough a quarter of a melon in one go, and he's managing just a couple of small triangles now.
He IS drinking - we manage to get a cup of milk down him before his bedtime and nap (with nesquick milkshake powder to add vitamins etc) and he will drink a small amount of water through the day - but even this amount has gone down over the last couple of days, and he would usually down a beakerfull (200ml) with no problem.
I am reluctant to take him to GP again - I had to call 111 last night as he had an episode of losing colour (a bit like a de-sat when he was a tiny baby in NICU) and first I got asked whether I was sure my thermometer was accurate (his temp was 39.2) and then told I shouldn't expect the abx to work overnight - I wasn't, I was calling about his colour change, which was a new symptom.
I'm happy that he is on meds for tonsillitis, and that his wee has been checked and is clear. It's pretty obvious his reluctance to eat is due to sore mouth/throat (he's also had a large mouth ulcer, which hasn't helped). But he is so skinny anyway that this 'not eating for a week' is making me very anxious and no health people seem bothered about it because he's still drinking. He's very pale and quite lethargic - as you would be with no nutrition.
What can I do? (Back story - he was a 27 week preemie with no ongoing issue, but has always been on lower centiles for weight and struggles to gain weight - he's 12kg)
