My broccoli and cabbage got true leaves fairly quickly, but my brussels sprouts did seem to stay small a lot longer. I germinated the BS inside, then kept the containers outside on a sheltered porch until they were ready to transplant. Here I thought maybe not growing them inside under lights was keeping them small, but it sounds like they just grow a lot more slowly than other brassicas.

When I transplanted them outside ~3 weeks after sowing, they were pretty tiny, with only 1 set of true leaves. Now a month later, they are closing in on a foot tall and looking great. Our cooler-than-usual summer must be agreeing with them.

Wow a foot in a month! I keep waiting for true leaves so I can pot them up, they are definitely slow growers!
