I fed him a couple of spoons of Hipp apple & blackberry yogurt before I noticed it smelt and tasted a bit like vinegar. Must admit though, never tried it before so not sure what it is supposed to taste like! However, instinct is telling me its gone off somehow (I dunno if the top button could be depressed before opening, I didn't check, was in a rush)...
He is sleeping now but I'm worried he is going to be very poorly. Can someone reassure me that the jar wasn't off and its normal for it to smell and taste like that?!
