Is your dd eating these food blw or puree?
I'm guessing that as she's 26 weeks you've only just started weaning, so maybe you need to give her less and slowly build the amount up.
If you are pureeing it is quite surprising how much food it takes to make a spoonful of puree.
I would also offer water, not a lot. Just a lidded beaker for her to learn what to do with it.
