Do your breastfed babies sleep through (at 6 months?)?

In all honesty both of kids were formula fed and they were/are bad sleepers. Formula doesn’t help them sleep more or longer stretches x

It’s very child dependent. My BF baby slept through from 6 weeks except when she was going through developmental sleep regressions, teething or poorly

I exclusively breastfed both of my babies until around 7/8 months. Initially when they switch to formula they still feed little and often because that's what they are used to, breastfed babies take awhile to adjust to a bigger feeds. But once they do, you definitely are up less often at night in my experience anyway.
