They're still young to eat fully. It's very normal. We also forget They're very tiny human with tiny stomach.
Was going to say what @Courtney said! It’s totally fine to let babe eat when they are hungry and stop when they want. I’ve worried also but milk really is/should be their main source of nutrition
My almost 8 month old wouldn’t eat anywhere near that amount. We’re struggling to get him to have any more than a couple of spoonfuls. I’m always worried he’s hungry but I’m sure they’d let you know if they were. I would just carry on with their usual milk and follow their cues
Food under one is just for fun as milk should still be his primary source of nutrition! Therefore I’d say it’s fine! ☺️
