When starting solids at 6 months, there is no set "rule" for quantity, as every baby’s appetite varies. Some parents find that their little ones consume around 50-100ml or half a baby bowl per meal, while others may eat very little at first. A good approach is to follow the baby's lead: offer food and allow them to eat as much as they are interested in, without force-feeding. Combining baby-led weaning exploration with small amounts of purees can help bridge the gap while they learn to eat.
