is it normal for 1 year old to refuse food even when it's offered on regular fixed meal times and intervals?

A. Hello good morning !! Yes its quite normal to reject solids/feed due to interest in playing . If baby only rejecting solids but having milk then might be texture issues or might be teething. Continue feeding semi solids,semi mashed & mashed foods plan a schedul,meanwhile offer finger foods - Vegetables chopped as fingers steam them ,fruits chopped into wedges or fingers by seeding. These will encourage taste buds having on own,they can explore more tastes,helps a lot in teething as these relievw in gum pain.
