Wife hesitant to give 11 month old anything but mashed foods. How do I ease her anxiety?

We have an 11 month old who is still eating only soft mashed foods (squash, peas and carrots, applesauce, sweet potato). My wife is the primary caregiver as a SAHM. She’s hesitant to try “more solid” solids out of fear of him choking. I’m worried that he’s not getting the opportunity to develop the proper physical skills associated with eating. Since everything is mashed he has not had finger foods yet and has no concept of how to put food in his mouth.

My wife offers him 40oz of formula a day - which I think is way too much at this age. I’ve tried to recommend her Solid Starts but she just disregarded the recommendation. She wants the best for our son, but I fear he’s not developing the skills needed for a soon to be 1 year old. She just recently started to let him crawl around in the bare floor, but only after I meticulously cleaned them.

Also, she has made it clear that our kid will have no added salt, no added sugars, no junk food until he’s at least 2. I think this is a bit extreme. I’m all for providing healthy meals to infants and children but I just feel it’s about balance.

I don’t know what to do to convince her otherwise. Maybe she’s right. Sorry for the rant, just looking for advice from some kind internet strangers.
