Eating

Baby has been fully weaning a while now, for the whole time weaning he cries when eating in a high chair like he’s really uncomfortable as if he’s got trapped wind sometimes he’ll burp instantly sometimes a little while after, we take him out instantly and feed him and he’s more comfortable. I don’t know if it’s how he’s sat in the high chair however he sits just how he should be, not to one side just up right like my older daughter. He’s really mobile, crawling, walking round furniture and walking with the walker. 5 mins in to eating in the high chair or seat he’s scrunches up like he’s in pain no matter what he eats like it just doesn’t go down right. I’m wondering if anyone else has experienced this and if so what did you do / use. We have the ikea high chair and then we also have a mamas and papas floor and booster seat at the table. Tonight I’ve had to following him round crawling and walking to feed him his dinner and he hasn’t been uncomfortable once. Really just want some help / advice. Thank you for reading.
