Weight gain, milk and solids intake for a weaning prem (slight panic)

Just reading previous threads over intake for babies at around 6 months. My daughter is a prem 7.5 months corrected age and 10.5 months actual. Normally quite calm about this but worrying a bit (ok a lot). Most recent weight gain is 350 grams this month.

I have genuinely believed her (a 27 weeker) to be a good feeder and also very much better (if better is the right word) at weaning than my first DD who went to term. I would really like to know if this sounds as if she is getting enough milk and food. She weighs 6.1kg (tiny but 900 gms at birth). Problems are that she is small so stomach is correspondingly small and I think her metabolism is also high. She is both active and lean in equal measure. She loves fruit, yoghurts, cereals, root veg (much like DD1). On advice of neonatal consultant have tried her on foods more equiv to a 10 month old (i.e. meat) this has not gone down so well so I've backed off - tbh my first daughter didn't want much to do with meat until 10months, maybe more. She will eat lumpier foods and I've given her cooked carrots etc and rice cakes to chew which she does really well with (she has one tooth!) - I wld have love to do BLW but I think that wld have been one step too far for the consultant and to be honest she needed the calories easily accessible from puree. He already views my BFing ways with some suspicion (she was EBF until 7 months actual).

I guess a 'usual' day looks like this:
Breast feed 6/7am
Porridge/fruit (biggest meal) takes a good 3 tablespoons
Formula milk (circa 100ml)
Mid morning breast feed
Lunchtime Veg w pasta/ potato (or usually mix of veg) and fruit (sometimes) w water
Formula milk (circa 100ml)
Mid afternoon Breast feed (longer BF)
Tea Veg followed by Yoghurt or banana w water
Bedtime Formula (140-160ml)
Night - was 1 BF, currently 2 BF (these are long good feeds)

Recently has been teething so not taking much at 'meal times' - more milk I think if my chest size anything to go by!

I am offering BM every so often in between the above times too although she tends to be on for 5 mins only - I guess a quick drink! It has been quite difficult to find info on weaning prems as I think it's such an unknown quantity. If anyone can guide me I'd be grateful - is she getting enough milk (firstly) and solids (secondly)? I feel I have more milk now than a month ago (I think?) owing to her now twice nightly feeding. TIA
