Is it Duocal? We were given a canister of that for our daughter. She is 5 now, but we have tried it all....Benecalorie, polycose, duocal, resource drinks......They didn't seem to be much of a help to us because she detected it in her food and drinks and didn't like it.
She's older, of course, so our main supplement is now just heavy cream. We add it to her milk and it's 50 calories per tablespoon....
