Can this day be over?

My problem is probably insignificant to some people but it’s bugging the hell out of me. I was a picky eater growing up, and now i’m paying for it. My toddler who is 20 months old is extremely picky. Like severely. Sometimes I think he does it to make it harder on me.

Today, I feed him 2 waffles, a handful of raspberries, and a banana for breakfast. This is our go to because I know he’ll finish it. He did.

Well for lunch I feed him chicken nuggets with barbecue sauce hoping he would like to dip it for fun and eat it. Nope. So I’m stuck feeding him snacks like animal crackers, gold fish, stuff like that. I hate this but I’d rather him eat something. Well dinner comes around and I make pizza because he literally had pizza this Saturday and guzzled it down. Nope. Not tonight. I’m stressing over here because my son is already below the 25th percentile. He’s 22lbs at 20 months old. He’s just now fitting 18 month clothing. His dad is 5’7 130 so he’s tiny himself so I think it’s partly genetic anyways. But still. How do I not stress? I obviously don’t want him to starve. But I’ve wasted so much food today. I’ve tried feeding him a yogurt, spaghetti Os. Like my kid would literally eat bread and fries all day for every meal if I let him. Or just junk. I don’t know what to do anymore. He won’t even drink milk. His dad doesn’t care whether or not he gets put to bed without eating and wants me to try it instead of offering other foods but I don’t want him having a bad relationship with food like I did. I was forced to eat stuff my family knew I didn’t like in hopes of me eating it but I never did and still don’t to this day. I don’t understand why my son has to be so difficult. I’m afraid of him dropping percentiles before the next visit and them thinking I starve him. I need suggestions or advice ladies.
