Toddlers a picky eater, help!

N

My son is 14 months old and is SO picky. He doesn’t like to eat any meat, and really all he likes to eat is: peanut butter and jelly sandwiches, lasagna, yogurt, and any fruit. He spits everything out of his mouth and is extremely stubborn. Trying to feed him has become a nightmare 😫 I need some suggestions !
