Not interested in solids

Lauren

We started my son on solids 3 weeks ago (he was just over 5 months old). He wasn’t super interested at the beginning and his feelings haven’t really changed about food. We’ve done cereal, carrots, sweet potato, apples, avocado. He doesn’t ever want to open his mouth when I try to give him a spoonful. Anyone else experience this? How long will it take for him to be more interested?
