Pay no attention.
In my experience, and in the experience of friends who demand fed feeding every 2-3 hours day and night until toddlerhood is common. Reverse cycling is common, and bursts every few weeks of feeding hourly for some chunks of the day or night is also common.
I cope with this with co-sleeping. Although I have an amby and can express milk for the odd night off as I enjoy the odd few drinks. Keeps me a bit saner!
Right now with 7 month old I feed every three hours or so in the day, bed at seven, feed at 11, then 12 (go figure!) then --- can't remember, she may sleep until 5am I guess, more leisurely feeding on and off from then.
You have to take a step back from the minutiae and how it looks though the fog of petty competitiveness, jealousy (ok, I'll admit with two children under 3.5 who were so-called 'bad sleepers' I'd like a big night off and some quality sleep) and tiredness.
They are babies and crave their parents, and if breastfed, crave their mothers. You can nudge them towards independence with greater or lesser force depending on where you stand on the parenting spectrum.
But there is no evidence that achieving a sleeping through/ self settling at a very young age benefits anyone save a frazzled parent.
So crowing about it is pointless and shows really that either you are lucky, or that you forced' a routine or some independence. So what.
Good luck, and you are not alone.
