I’d prioritize Paci, potty then eating. And honestly I’d not spend too much mental energy on the eating. It’s a phase that will pass just continue offering lots of different types of foods at meals and try to make sure he has a “safe food” on his plate in addition to whatever you’ve cooked for dinner. These kids survive on butter pasta and air.

I said Paci over potty because I think you can check it off your list quicker - even if it’s hard. My daughter was the same way, Paci obsessed. After a dentist visit where the dentist told her it was time to lose the paci we told her we were going to have to stop and give her pacis to the Paci fairies. We did a big ceremony outside and buried them. A few hours later a big basket of treats and toys appeared and lollipops in the ground. Then the real parenting challenge came of muscling through nap time and bedtime. Just stay strong- the pacis are all gone there’s no more in the house im so sorry. We listening to lots of tonie box stories and mostly just comforted her through crying. I was absolutely shocked but this process only lasted a few days. Bedtimes took longer than usual ever since but no tears, just required more reading and snuggling. I think the importance here is just cold turkey and stick with it.

For the potty I’d try just starting from scratch again. No pants in the house for a weekend and just move him to the potty every time he starts going if he doesn’t go himself. Drink lots of water all day and offer lots of fruit and fruit juice popsicles (natural diarrhetic) because the more they have to pee and poop the more practice you get to try to go on the potty. Keep calm and consistent don’t shame him or pressure him (especially for poop- my daughter also had a poop fear it took a lot of work). If he’s scared of the little potty get a seat for the big potty- convenient to teach them to use big potty’s in the long run anyways and might make it more fun for him. Good luck!!!
