She won't eat fresh fruits/veggies & development check-in

My (soon to be) 18 m/o daughter hardly ever eats fresh fruits or veggies. I feel like so many toddlers her age are great with cut up fruit (at least) as finger foods, however she won't even try them. I know it's not a taste issue because she'll down a fruit and veggies pouch or granola bar, etc. no problem...it seems like maybe it's a texture thing? I just feel like she eats a lot of processed food as a result (granted we try to buy organic toddler snack foods with minimal ingredients), and she is a little on the small side for her age (22lbs), so I'm starting to worry about her growth and development. Anyone else have a similar issue?

Also, speaking of development, what is your LO doing great with, or struggling with, in the 16-20 month age range?
