that's not good

seriously, if possible, I would be sitting with her and making sure she eats just like if she were 3 years old , every meal

or a nurse

Try something called Sustagen. I've used it in the past when I needed to put on weight due to a degree of malnourishment.

Have seen them used as doorstops, at which they are very effective. Being stable in multiple aspects.

Best of luck with the weight gain. It's so hard 🫂

Does she like or tolerate sweet flavours? Is there any ability to chew (and able to swallow soft solids)? Because if yes to one or both the options expand exponentially

Sugar is very helpful for calories and solids might be more variety

Ooh! Covet the last.

Wishing you so much luck with the food thing!
