Very little appetite … like always

My little boy will be 2 on the 19th! ❤️ But I swear this boy barely eats but he’s always teetering right in the 50th percentiles for everything. He’s about 33 inches tall and 27 lbs.

Since 6 months when we began feeding him food other than formula, he just eats so little. Some days (very seldom) he will eat well but most days I can’t believe how little he eats. I’ve told his pediatrician and they’re not very concerned, just keep telling me to try more variety which I do, and to make sure to feed him things that I know he will usually eat. But the last week or so it’s been so bad that he’ll eat nothing but a slice of cheese and a pickle all day long.

One exception is sugar, he loves sweets. Cookies/ice cream/ popsicles/etc. which I hate to give him but he gets some every day especially because he barely eats. He likes appetizer platters like nuggets, macaroni bites and stuff and he loves cheese and pickles but still doesn’t eat much of that. I make him popsicles out of fruit/veggie blended baby food and I also try to give him those fruit/veggie v8 juices. He’s a happier boy than when he was an infant now (thank god) and is active and doesn’t even nap most of the time. He’s also talking great and been walking since 10 months even despite the torticollis difficulties we’ve had.

I’m just worried my baby isn’t getting his nutrients. I began researching supplemental shakes and things, and I also have never given him vitamins which his pediatrician has asked if he takes any and when I say no has never particularly recommended it or not so I wasn’t very worried. Anybody in a similar situation or have any tips? Thanks!
