Feeding in the first year of life why introducing solids matters?
Research doesn’t support the idea that solids improve sleep, so don’t let anyone pressure you into starting solids sooner than 17 weeks, ideally waiting until six months of age.
Breastmilk (or formula) is the main source of nutrition for your baby until they turn one year.
Baby-led feeding is a great approach — cuts down on extra cooking, but not necessarily the mess. There is no research to back up the need of follow-on milk.
