Firstly I’d drop a bottle, she doesn’t need 3 bottles a day, she online y needs 300 ml and anything above that could be exacerbating the problems.
No vomiting isn’t normal and I’d talk to your HV about that again. My DS struggled with lumps and solid food but his problem turned out to be tongue tie. Do any of the symptoms on the list sound familiar?
I’m not surprised that she’s refusing savoury food too. Even the reduced sugar risks are one fifth added sugar and Ella’s pouches are full of natural sugars too. Babies get a taste for the first foods they are given and yours seems to have been given a lot of sugar 
. I agree with the HV, definitely stop the Ella’s pouches, she’s not going to learn to eat normal family food if she can just suck on some sugary gloop.
Refusing food after a few spoonfuls is perfectly normal too. At one she can regulate her own food intake and you should let her do this. It’s your job to offer the food but she doesn’t have to eat it. Plus if you look at it like she is just self regulating, it will take the pressure off you when she’s indicated she’s had enough. You have to trust her on this one. Try to prepare meals that you can all enjoy so it doesn’t feel like a wasted effort on your part if she doesn’t eat much. Babies generally eat tiny amounts anyway. Do you think that keeping a log of what she eats over a week would help you? Some days babies eat like sparrows and other days they can eat much more. If you look on what she’s eaten over the week rather than focusing on eat meal, this can also help to elevate your worry when she’s fussy over one particular meal.
If you are after some suggestions of meals, try some of these:
Breakfast
Oatibix with whole milk and raisins
Sausage (cut lengthways) and baked beans
Blueberry pancakes (can be frozen but we normally just scoff them all).
Cheese on toast.
Smooth nut butter on toast.
A banana and some other fresh fruit.
Egg and soldiers.
French toast.
Porridge fingers.
Lunch
Sardines on toast
Salmon fish cakes and veg
Sandwich and raw veg
Savoury muffin and raw veg.
Bean burger.
Dinner
Fish pie.
Spag Bol (I’d put her in a long sleeved bib and put a cheap shower curtain on the floor, it can get messy)
Roast dinner.
Curry (you can make them milder by added natural yoghurt to hers)
Roast chicken/poached salmon with new potatoes and salad.
Chicken wraps
Posh dogs
Homemade pizza.
If choking is a major concern, have you been on a Paediatric First Aid Course? If not, I’d really recommend going on one. Are you this anxious about any other aspect of parenting? If you are I’d recommend speaking to your GP tomorrow. The high level of anxiety that you’ve eclressed isn’t usual and can be a symptom of PNI, your GP may be able to help you.
