My baby burping more while having solid food what causes to accumulate air while having solid food.?

A. Try to feed your baby in a more upright position. Hold your baby upright for up to 20 minutes after each feed. Try giving your baby smaller feeds more often. If you bottle-feed your baby, try to minimise the amount of air he swallows. Tilt the bottle so that the milk completely fills the teat before offering it to your baby. You could also consider an anti-colic bottle.
