daphne,
perhaps you can let bb U sit at the dining table with you and both of you sort of eat dinner at the same time? When M fusses and refuse to eat, I will do that and sort of feed her as I eat my dinner. Also try giving U his food out of your plate, esp if you are eating food that he can eat too. M deson't quite care for salmon, but if I am eating some and gave some to her (using the same plate and fork that I am using), she will be more receptive.
Lastly, if all else fails, you might want to try deception. M loves water and puffs, so I will pretend to give her some and when mouth is open, quickly pops in a spoonful of her food.
I can imagine how stress you are, I am paranoid about M's food intake also, esp since she is so small. But bbs can sense and react to our emotions. I always tell myself, if M is hungry, she will cry. So I will feed her then,
Oh, in my attempt to stuff her with more milk, I am still dreamfeeding her at 11pm.
So you try and relax yah (I know it's easier said than done). Ugin will be fine
*hugs*!!
