picky eaters - 1 year old

Erin
Hello! My son will soon be 14 months old and he's still super picky about eating solid foods. We have to feed him a Purée and will accompany it with some sort of solid food (just to make sure he gets something to eat)
I feel like by now he should be eating mostly solids and picking up a variety of diff foods and eating them but isn't. Anyone else have a super picky eater and have suggestions or advice how to get them to eat more solids?
