10 month olds feeding help

if you’ve had experience with this please give me some examples of how you handled it

I have a 10 month old boy ** we see the pediatrician every 2 weeks for a weight check**

I have a hard time getting him to eat more than 24 oz a day of formula I’ve tried cups, sippy cups, bottles basically anything I’ve even gone to using a syringe to just get fluid in him

The pediatric wants him to start eating soft foods but how do I keep his formula intake up plus soft foods he does really good with soft foods But he has to have formula

so what did you do to help your baby keep up with formula plus soft food??
