Introducing Solids can Help
By the time your child is 6 months old, they should be able to start sleeping through the night – if you go about things the right way. The main reason is because solids can be introduced at this point.
Solid foods aren’t digested as quickly as formula or breast milk, which means that your little one will feel full longer and won’t need to feed as much during the night, if at all.
Introducing solids can also help with the weaning process. Your child may be more interested in trying new foods rather than breastfeeding or taking a bottle. And the fact that they stay full longer means that they won’t need to nurse as often.
