My seven month old stopped taking solids

I started solids at 4 months very sporadically. At 6 months he was doing okay with 2 oz of solid food a day. Then he started to finish 4oz through out the whole day. Now about 2 weeks ago he stopped taking solids at all. He doesn’t like he usual favorite flavor or any new solids. I’m getting worried. Is this normal? He is breastfeed if that makes any difference.
