Hello moms. Can you tell me who gave this cookie? I suspect it's him (only in the yellow package, I haven't tried the blue one). Because for several days he started scratching his eyes and head. And the bottom became red and doesn't go away. At first, I blamed diapers. Now I understand that it's an allergy. What should I do? And what kind of cookie was given without problems, we have been having it for 5 months.
