I feel like older generations are always saying things like, Oh she will sleep through the night once she has a little rice in her belly. But I don't get the impression that this is really the case. These are usually the same people who think breastfeeding past 6 months is 'extended breastfeeding' and that breast milk isn't enough, in my experience.

Did it change sleep habits for you when your LO started on solids? C is only 4.5 months and not showing any signs of being really ready for solids yet anyway.
