He doesn't like the peas or the circular brown things, i watched a youtuber (Erinsanimals) and she suggested to not give it anymore food until he's eaten what he has but he didn't eat very much and then I got a little worried because it was a few days later (I only got him a week ago tomorrow) should I be worried or is there something else which I should do and how much am I meant to feed him a day/ how often should I feed him?
