1 year old won't eat !!

Sesme • ✨Mama Bear✨💝
My 1 year old won't eat any meals !! Or vegetables or anything like that ! He's being very picky about his foods now and I'm starting to worry about him not eating. He prefers sweets such as candy and I don't give it to him myself but his grandma does and my sisters and a few others even when I say NO ! Anybody knows what I can do for this ??
